[analyzer] This patch removes passing around of const-invalidation vs regular-invalidation info by passing around a datastructure that maps regions and symbols to the type of invalidation they experience. This simplifies the code and would allow to associate more different invalidation types in the future.
With this patch things like preserving contents of regions (either hi- or low-level ones) or processing of the only top-level region can be implemented easily without passing around extra parameters.
This patch is a first step towards adequate modeling of memcpy() by the CStringChecker checker and towards eliminating of majority of false-positives produced by the NewDeleteLeaks checker.

[analyzer] Fix inefficiency in dead symbol removal
Summary:
ScanReachableSymbols uses a "visited" set to avoid scanning the same object
twice. However, it did not use the optimization for LazyCompoundVal objects,
which resulted in exponential complexity for long chains of temporary objects.
Adding this resulted in a decrease of analysis time from >3h to 3 seconds for
some files.

[analyzer] Ensure BugReporterTracking works on regions with pointer arithmetic
Introduce a new helper function, which computes the first symbolic region in
the base region chain. The corresponding symbol has been used for assuming that
a pointer is null. Now, it will also be used for checking if it is null.
This ensures that we are tracking a null pointer correctly in the BugReporter.

[analyzer] Replace isIntegerType() with isIntegerOrEnumerationType().
Previously, the analyzer used isIntegerType() everywhere, which uses the C
definition of "integer". The C++ predicate with the same behavior is
isIntegerOrUnscopedEnumerationType().
However, the analyzer is /really/ using this to ask if it's some sort of
"integrally representable" type, i.e. it should include C++11 scoped
enumerations as well. hasIntegerRepresentation() sounds like the right
predicate, but that includes vectors, which the analyzer represents by its
elements.
This commit audits all uses of isIntegerType() and replaces them with the
general isIntegerOrEnumerationType(), except in some specific cases where
it makes sense to exclude scoped enumerations, or any enumerations. These
cases now use isIntegerOrUnscopedEnumerationType() and getAs<BuiltinType>()
plus BuiltinType::isInteger().
isIntegerType() is hereby banned in the analyzer - lib/StaticAnalysis and
include/clang/StaticAnalysis. :-)

[analyzer] Properly handle the ternary operator in trackNullOrUndefValue
1) Look for the node where the condition expression is live when checking if
it is constrained to true or false.
2) Fix a bug in ProgramState::isNull, which was masking the problem. When
the expression is not a symbol (,which is the case when it is Unknown) return
unconstrained value, instead of value constrained to “false”!
(Thankfully other callers of isNull have not been effected by the bug.)

[analyzer] Teach invalidateRegions that regions within LazyCompoundVal need to be invalidated
Refactor invalidateRegions to take SVals instead of Regions as input and teach RegionStore
about processing LazyCompoundVal as a top-level “escaping” value.
This addresses several false positives that get triggered by the NewDelete checker, but the
underlying issue is reproducible with other checkers as well (for example, MallocChecker).

[analyzer] Add support for escape of const pointers and use it to allow “newed” pointers to escape
Add a new callback that notifies checkers when a const pointer escapes. Currently, this only works
for const pointers passed as a top level parameter into a function. We need to differentiate the const
pointers escape from regular escape since the content pointed by const pointer will not change;
if it’s a file handle, a file cannot be closed; but delete is allowed on const pointers.
This should suppress several false positives reported by the NewDelete checker on llvm codebase.

[analyzer] Invalidate regions indirectly accessible through const pointers.
In this case, the value of 'x' may be changed after the call to indirectAccess:
struct Wrapper {
int *ptr;
};
void indirectAccess(const Wrapper &w);
void test() {
int x = 42;
Wrapper w = { x };
clang_analyzer_eval(x == 42); // TRUE
indirectAccess(w);
clang_analyzer_eval(x == 42); // UNKNOWN
}
This is important for modelling return-by-value objects in C++, to show
that the contents of the struct are escaping in the return copy-constructor.

[analyzer] Simple inline defensive checks suppression
Inlining brought a few "null pointer use" false positives, which occur because
the callee defensively checks if a pointer is NULL, whereas the caller knows
that the pointer cannot be NULL in the context of the given call.
This is a first attempt to silence these warnings by tracking the symbolic value
along the execution path in the BugReporter. The new visitor finds the node
in which the symbol was first constrained to NULL. If the node belongs to
a function on the active stack, the warning is reported, otherwise, it is
suppressed.
There are several areas for follow up work, for example:
- How do we differentiate the cases where the first check is followed by
another one, which does happen on the active stack?
Also, this only silences a fraction of null pointer use warnings. For example, it
does not do anything for the cases where NULL was assigned inside a callee.

Sort all of Clang's files under 'lib', and fix up the broken headers
uncovered.
This required manually correcting all of the incorrect main-module
headers I could find, and running the new llvm/utils/sort_includes.py
script over the files.
I also manually added quite a few missing headers that were uncovered by
shuffling the order or moving headers up to be main-module-headers.

[analyzer] Move convenience REGISTER_*_WITH_PROGRAMSTATE to CheckerContext.h
As Anna pointed out, ProgramStateTrait.h is a relatively obscure header,
and checker writers may not know to look there to add their own custom
state.
The base macro that specializes the template remains in ProgramStateTrait.h
(REGISTER_TRAIT_WITH_PROGRAMSTATE), which allows the analyzer core to keep
using it.

Reapply "[analyzer] Remove constraints on dead symbols as part of removeDeadBindings."
Previously, we'd just keep constraints around forever, which means we'd
never be able to merge paths that differed only in constraints on dead
symbols.
Because we now allow constraints on symbolic expressions, not just single
symbols, this requires changing SymExpr::symbol_iterator to include
intermediate symbol nodes in its traversal, not just the SymbolData leaf
nodes.
This depends on the previous commit to be correct. Originally applied in
r163444, reverted in r164275, now being re-applied.

Revert "[analyzer] Remove constraints on dead symbols as part of removeDeadBindings."
While we definitely want this optimization in the future, we're not
currently handling constraints on symbolic /expressions/ correctly.
These should stay live even if the SymExpr itself is no longer referenced
because could recreate an identical SymExpr later. Only once the SymExpr
can no longer be recreated -- i.e. a component symbol is dead -- can we
safely remove the constraints on it.
This liveness issue is tracked by <rdar://problem/12333297>.

Remove ProgramState::getSymVal(). It was being misused by Checkers,
with at least one subtle bug in MacOSXKeyChainAPIChecker where the
calling the method was a substitute for assuming a symbolic value
was null (which is not the case).
We still keep ConstraintManager::getSymVal(), but we use that as
an optimization in SValBuilder and ProgramState::getSVal() to
constant-fold SVals. This is only if the ConstraintManager can
provide us with that information, which is no longer a requirement.
As part of this, introduce a default implementation of
ConstraintManager::getSymVal() which returns null.
For Checkers, introduce ConstraintManager::isNull(), which queries
the state to see if the symbolic value is constrained to be a null
value. It does this without assuming it has been implicitly constant
folded.

[analyzer] Correctly devirtualize virtual method calls in destructors.
C++11 [class.cdtor]p4: When a virtual function is called directly or
indirectly from a constructor or from a destructor, including during
the construction or destruction of the class’s non-static data members,
and the object to which the call applies is the object under
construction or destruction, the function called is the final overrider
in the constructor's or destructor's class and not one overriding it in
a more-derived class.

The main blocker on this (besides the previous commit) was that
ScanReachableSymbols was not looking through LazyCompoundVals.
Once that was fixed, it's easy enough to clear out malloc data on return,

[analyzer] Revamp RegionStore to distinguish regions with symbolic offsets.
RegionStore currently uses a (Region, Offset) pair to describe the locations
of memory bindings. However, this representation breaks down when we have
regions like 'array[index]', where 'index' is unknown. We used to store this
as (SubRegion, 0); now we mark them specially as (SubRegion, SYMBOLIC).
Furthermore, ProgramState::scanReachableSymbols depended on the existence of
a sub-region map, but RegionStore's implementation doesn't provide for such
a thing. Moving the store-traversing logic of scanReachableSymbols into the
StoreManager allows us to eliminate the notion of SubRegionMap altogether.
This fixes some particularly awkward broken test cases, now in
array-struct-region.c.

Instead of sprinkling dynamic type info propagation throughout
ExprEngine, the added checker would add the more precise type

not implemented yet)).

[analyzer] Introduce a CallEventManager to keep a pool of CallEvents.
This allows us to get around the C++ "virtual constructor" problem
when we'd like to create a CallEvent from an ExplodedNode, an inlined
StackFrameContext, or another CallEvent. The solution has three parts:
- CallEventManager uses a BumpPtrAllocator to allocate CallEvent-sized
memory blocks. It also keeps a cache of freed CallEvents for reuse.
- CallEvents all have protected copy constructors, along with cloneTo()
methods that use placement new to copy into CallEventManager-managed
memory, vtables intact.
- CallEvents owned by CallEventManager are now wrapped in an
IntrusiveRefCntPtr. Going forwards, it's probably a good idea to create
ALL CallEvents through the CallEventManager, so that we don't accidentally
try to reclaim a stack-allocated CallEvent.
All of this machinery is currently unused but will be put into use shortly.

[analyzer] Use CallEvent for building inlined stack frames.
In order to accomplish this, we now build the callee's stack frame

This should not have any effect on perceived behavior or diagnostics.

[analyzer] Add a new abstraction over all types of calls: CallEvent
This is intended to replace CallOrObjCMessage, and is eventually intended to be
used for anything that cares more about /what/ is being called than /how/ it's
being called. For example, inlining destructors should be the same as inlining
blocks, and checking __attribute__((nonnull)) should apply to the allocator
calls generated by operator new.

[analyzer] Make the entries in 'Environment' context-sensitive by making entries map from
(Stmt*,LocationContext*) pairs to SVals instead of Stmt* to SVals.
This is needed to support basic IPA via inlining. Without this, we cannot tell
if a Stmt* binding is part of the current analysis scope (StackFrameContext) or
part of a parent context.
This change introduces an uglification of the use of getSVal(), and thus takes
two steps forward and one step back. There are also potential performance implications
of enlarging the Environment. Both can be addressed going forward by refactoring the
APIs and optimizing the internal representation of Environment. This patch
mainly introduces the functionality upon when we want to build upon (and clean up).

[analyzer] Be less pessimistic about invalidation of global variables
as a result of a call.
Problem:
Global variables, which come in from system libraries should not be
invalidated by all calls. Also, non-system globals should not be
invalidated by system calls.
Solution:
The following solution to invalidation of globals seems flexible enough
for taint (does not invalidate stdin) and should not lead to too
many false positives. We split globals into 3 classes:
* immutable - values are preserved by calls (unless the specific
global is passed in as a parameter):
A : Most system globals and const scalars
* invalidated by functions defined in system headers:
B: errno
* invalidated by all other functions (note, these functions may in
turn contain system calls):
B: errno
C: all other globals (which are not in A nor B)

[analyzer] Refactor: Move symbol_iterator from SVal to SymExpr, use it
for finding dependent symbols for taint.

[analyzer] Propagate taint through NonLoc to NonLoc casts.
- Created a new SymExpr type - SymbolCast.
- SymbolCast is created when we don't know how to simplify a NonLoc to
NonLoc casts.
- A bit of code refactoring: introduced dispatchCast to have better
code reuse, remove a goto.
- Updated the test case to showcase the new taint flow.

[analyzer] Remove all uses of ConstraintManager::canResonAbout() from
ExprEngine.
Teach SimpleConstraintManager::assumeSymRel() to propagate constraints
to symbolic expressions.
+ One extra warning (real bug) is now generated due to enhanced
assumeSymRel().

[analyzer] Add ability to do a simple ProgramState dump() without
requiring CFG.
Adding more ugly code; the evnvironment printing should be moved to
envirnment at some point.

[analyzer] Adding basic building blocks for taint propagation.
TaintTag.h will contain definitions of different taint kinds and their properties.
TaintManager will be responsible for implementing taint specific operations, storing taint.
ProgramState will provide API to add/remove taint.

ST->scanReachableSymbols() is creating a SubRegionMap (SRM) on every call since one SRM is created in each ScanReachableSymbols instance. Creating the object just once and calling only scan inside the loop gives ~ 14% speed up of the StaticAnalyzer run (Release+Asserts).
Pull out the declaration of the ScanReachableSymbols so that it can be used directly. Document ProgramState::scanReachableSymbols() methods.

[analyzer] Remove TransferFuncs.h, then deal with the fallout.
And with that, TransferFuncs is gone!

[analyzer] Introduce a new callback for checkers, printState, to be used for debug-printing the contents of a ProgramState.
Unlike the other callbacks, this one is a simple virtual method, since it is only to be used for debugging.
This new callback replaces the old ProgramState::Printer interface, and allows us to move the printing of refcount bindings from CFRefCount to RetainReleaseChecker.

[analyzer] Change the check::RegionChanges callback to include the regions explicitly requested for invalidation.
Also, allow CallOrObjCMessage to wrap a CXXConstructExpr as well.
Finally, this allows us to remove the clunky whitelisting system from CFRefCount/RetainReleaseChecker. Slight regression due to CXXNewExprs not yet being handled in post-statement callbacks (PR forthcoming).
