Revert "[analyzer] Break cycles (optionally) when trimming an ExplodedGraph."
The algorithm used here was ridiculously slow when a potential back-edge
pointed to a node that already had a lot of successors. The previous commit
makes this feature unnecessary anyway.
This reverts r177468 / f4cf6b10f863b9bc716a09b2b2a8c497dcc6aa9b.

[analyzer] Break cycles (optionally) when trimming an ExplodedGraph.
Having a trimmed graph with no cycles (a DAG) is much more convenient for
trying to find shortest paths, which is exactly what BugReporter needs to do.

[analyzer] Recover all PreStmtPurgeDeadSymbols nodes with a single successor or predecessor.
These nodes are never consulted by any analyzer client code, so they are
used only for machinery for removing dead bindings. Once successor nodes
are generated they can be safely removed.
This greatly reduces the amount of nodes that are generated in some case,
lowering the memory regression when analyzing Sema.cpp introduced by
r176010 from 14% to 2%.

[analyzer] add the notion of an "interesting" lvalue expression for ExplodedNode pruning.

only "interesting" expressions that would be used for diagnostics.

[analyzer] tracking stores/constraints now works for ObjC ivars or struct fields.
This required more changes than I originally expected:
- ObjCIvarRegion implements "canPrintPretty" et al
- DereferenceChecker indicates the null pointer source is an ivar
- bugreporter::trackNullOrUndefValue() uses an alternate algorithm
to compute the location region to track by scouring the ExplodedGraph.
This allows us to get the actual MemRegion for variables, ivars,
fields, etc. We only hand construct a VarRegion for C++ references.
- ExplodedGraph no longer drops nodes for expressions that are marked
'lvalue'. This is to facilitate the logic in the previous bullet.
This may lead to a slight increase in size in the ExplodedGraph,
which I have not measured, but it is likely not to be a big deal.
I have validated each of the changed plist output.

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] Use the CallEnter node to get a value for tracked null arguments.
Additionally, don't collect PostStore nodes -- they are often used in
path diagnostics.
Previously, we tried to track null arguments in the same way as any other
null values, but in many cases the necessary nodes had already been
collected (a memory optimization in ExplodedGraph). Now, we fall back to
using the value of the argument at the time of the call, which may not
always match the actual contents of the region, but often will.
This is a precursor to improving our suppression heuristic.

[analyzer] Replace -analyzer-no-eagerly-trim-egraph with graph-trim-interval.
After every 1000 CFGElements processed, the ExplodedGraph trims out nodes
that satisfy a number of criteria for being "boring" (single predecessor,
single successor, and more). Rather than controlling this with a cc1 option,
which can only disable this behavior, we now have an analyzer-config option,
'graph-trim-interval', which can change this interval from 1000 to something
else. Setting the value to 0 disables reclamation.
The next commit relies on this behavior to actually test anything.

[analyzer] Allow a BugReport to be marked "invalid" during path generation.
This is intended to allow visitors to make decisions about whether a
BugReport is likely a false positive. Currently there are no visitors
making use of this feature, so there are no tests.
When a BugReport is marked invalid, the invalidator must provide a key
that identifies the invaliation (intended to be the visitor type and a
context pointer of some kind). This allows us to reverse the decision
later on. Being able to reverse a decision about invalidation gives us more
flexibility, and allows us to formulate conditions like "this report is
invalid UNLESS the original argument is 'foo'". We can use this to
fine-tune our false-positive suppression (coming soon).

[analyzer] Add new PreImplicitCall and PostImplicitCall ProgramPoints.
These are currently unused, but are intended to be used in lieu of PreStmt
and PostStmt when the call is implicit (e.g. an automatic object destructor).
This also modifies the Data1 field of ProgramPoints to allow storing any
pointer-sized value, as opposed to only aligned pointers. This is necessary
to store SourceLocations.
There is currently no BugReporter support for these; they should be skipped
over in any diagnostic output.
This commit also tags checkers that currently rely on function calls only
occurring at StmtPoints.

[analyzer] Move the last bits of CallOrObjCMessage over to CallEvent.
This involved refactoring some common pointer-escapes code onto CallEvent,
then having MallocChecker use those callbacks for whether or not to consider
a pointer's /ownership/ as escaping. This still needs to be pinned down, and
probably we want to make the new argumentsMayEscape() function a little more
discerning (content invalidation vs. ownership/metadata invalidation), but
this is a good improvement.
As a bonus, also remove CallOrObjCMessage from the source completely.

[analyzer] Fix a spurious undef value warning.
When we timeout or exceed a max number of blocks within an inlined
function, we retry with no inlining starting from a node right before
the CallEnter node. We assume the state of that node is the state of the
program before we start evaluating the call. However, the node pruning
removes this node as unimportant.
Teach the node pruning to keep the predecessors of the call enter nodes.

[analyzer] Run remove dead bindings right before leaving a function.
This is needed to ensure that we always report issues in the correct
function. For example, leaks are identified when we call remove dead
bindings. In order to make sure we report a callee's leak in the callee,
we have to run the operation in the callee's context.
This change required quite a bit of infrastructure work since:
- We used to only run remove dead bindings before a given statement;
here we need to run it after the last statement in the function. For
this, we added additional Program Point and special mode in the
SymbolReaper to remove all symbols in context lower than the current
one.
- The call exit operation turned into a sequence of nodes, which are
now guarded by CallExitBegin and CallExitEnd nodes for clarity and
convenience.

Reduce peak memory usage of the static analyzer on sqlite3 (when using inlining) by 30%.
This is accomplished by periodically reclaiming nodes in the graph. This was an optimization
done before the CFG was linearized, but the CFG linearization destroyed that optimization since each
freshly created node couldn't be reclaimed and we only looked at a window of nodes created between
each ProcessStmt. This optimization can be reclaimed my merely expanding the window to N number of nodes.

Remove '#if 0' from ExprEngine::InlineCall(), and start fresh by wiring up inlining for straight C calls.
My hope is to reimplement this from first principles based on the simplifications of removing unneeded node builders
and re-evaluating how C++ calls are handled in the CFG. The hope is to turn inlining "on-by-default" as soon as possible
with a core set of things working well, and then expand over time.

[analyzer] Make sink attribute part of the node profile.
This prevents caching out on nodes with different sink flag.
(This is a cleaner fix for radar://10376675).

Cleanup various declarations of 'Stmt*' to be 'Stmt *', etc. in libAnalyzer and libStaticAnalyzer[*]. It was highly inconsistent, and very ugly to look at.

Split 'include/clang/StaticAnalyzer' into 'include/clang/StaticAnalyzer/Core' and 'include/clang/StaticAnalyzer/Checkers'.
This layout matches lib/StaticAnalyzer, which corresponds to two StaticAnalyzer libraries.

static analyzer: Further reduce the analyzer's memory usage when analyzing sqlite3 by 7-10% by recylcing "uninteresting" ExplodedNodes.
The optimization involves eagerly pruning ExplodedNodes from the ExplodedGraph that contain
practically no difference between the predecessor and successor nodes. For example, if
the state is different between a predecessor and a node, the node is left in. Only for
the 'environment' component of the state do we not care if the ExplodedNodes are different.
This paves the way for future optimizations where we can reclaim the environment objects.

[analyzer] Move the files in lib/StaticAnalyzer to lib/StaticAnalyzer/Core.
Eventually there will also be a lib/StaticAnalyzer/Frontend that will handle initialization and checker registration.
Yet another library to avoid cyclic dependencies between Core and Checkers.
