Implement the all_lookups_iterator for PCH as a follow-up to r153970. This
includes a patch from Matthias Kleine with a regression testcase!
Adds a new iterator 'data_iterator' to OnDiskHashTable which doesn't try to
reconstruct the external_key from the internal_key, which is useful for traits
that don't store enough information to do that mapping in their key. Also
deletes the 'item_iterator' from OnDiskHashTable as dead code.

Extend the ExternalASTSource interface to allow the AST source to
provide the layout of records, rather than letting Clang compute
the layout itself. LLDB provides the motivation for this feature:
because various layout-altering attributes (packed, aligned, etc.)
don't get reliably get placed into DWARF, the record layouts computed
by LLDB from the reconstructed records differ from the actual layouts,
and badness occurs. This interface lets the DWARF data drive layout,
so we don't need the attributes preserved to get the answer write.
The testing methodology for this change is fun. I've introduced a
variant of -fdump-record-layouts called -fdump-record-layouts-simple
that always has the simple C format and provides size/alignment/field
offsets. There is also a -cc1 option -foverride-record-layout=<file>
to take the output of -fdump-record-layouts-simple and parse it to
produce a set of overridden layouts, which is introduced into the AST
via a testing-only ExternalASTSource (called
LayoutOverrideSource). Each test contains a number of records to lay
out, which use various layout-changing attributes, and then dumps the
layouts. We then run the test again, using the preprocessor to
eliminate the layout-changing attributes entirely (which would give us
different layouts for the records), but supplying the
previously-computed record layouts. Finally, we diff the layouts
produced from the two runs to be sure that they are identical.
Note that this code makes the assumption that we don't *have* to
provide the offsets of bases or virtual bases to get the layout right,
because the alignment attributes don't affect it. I believe this
assumption holds, but if it does not, we can extend
LayoutOverrideSource to also provide base offset information.
Fixes the Clang side of <rdar://problem/10169539>.

Don't force the complete deserialization of the visible-declarations
table when serializing an AST file. This was a holdover from the days
before chained PCH, and is a complete waste of time and storage
now. It's a good thing it's useless, because I have no idea how I
would have implemented MaterializeVisibleDecls efficiently in the
presence of modules.

Introduce a new data structure, LazyVector, which is a vector whose
contents are lazily loaded on demand from an external source (e.g., an
ExternalASTSource or ExternalSemaSource). The "loaded" entities are
kept separate from the "local" entities, so that the two can grow
independently.
Switch Sema::TentativeDefinitions from a normal vector that is eagerly
populated by the ASTReader into one of these LazyVectors, making the
ASTReader a bit more like me (i.e., lazy).

Extend ExternalASTSource with the ability to lazily complete the
definition of an Objective-C class. Unlike with C/C++ classes, we
don't have a well-defined point in Sema where Objective-C classes are
checked for completeness, nor do we need to involve Sema when
completing a class. Therefore, we take the appropriate of having the
external AST source mark a particular Objective-C class as having an
external declaration; when using one of the accessors of an
Objective-C class that has an external declaration, we request that
the external AST source fill in the Objective-C class definition.

Allow deserialization of just the fields of a record, when we want to iterate over them,
instead of deserializing the complete declaration context of the record.
Iterating over the fields of a record is very common (e.g to determine the layout), unfortunately we needlessly deserialize every declaration
that the declaration context of the record contains; this can be bad for large C++ classes that contain a lot of methods.
Fix this by allow deserialization of just the fields when we want to iterate over them.

Fix an issue with writing to PCH another included PCH, introduced by the "using an AST on-disk hash table for name lookup" commit.
When including a PCH and later re-emitting to another PCH, the name lookup tables of DeclContexts
may be incomplete, since we now lazily deserialize the visible decls of a particular name.
Fix the issue by iterating over the un-deserialized visible decls and completing the lookup tables
of DeclContexts before writing them out.

Alter the ExternalASTSource interface to permit by-name lookups. PCH continues to
bring in the entire lookup table at once.
Also, give ExternalSemaSource's vtable a home. This is important because otherwise
any reference to it will cause RTTI to be emitted, and since clang is compiled
with -fno-rtti, that RTTI will contain unresolved references (to ExternalASTSource's
RTTI). So this change makes it possible to subclass ExternalSemaSource from projects
compiled with RTTI, as long as the subclass's home is compiled with -fno-rtti.

Add support for retrieving the Doxygen comment associated with a given
declaration in the AST.
The new ASTContext::getCommentForDecl function searches for a comment
that is attached to the given declaration, and returns that comment,
which may be composed of several comment blocks.
Comments are always available in an AST. However, to avoid harming
performance, we don't actually parse the comments. Rather, we keep the
source ranges of all of the comments within a large, sorted vector,
then lazily extract comments via a binary search in that vector only
when needed (which never occurs in a "normal" compile).
Comments are written to a precompiled header/AST file as a blob of
source ranges. That blob is only lazily loaded when one requests a
comment for a declaration (this never occurs in a "normal" compile).
The indexer testbed now supports comment extraction. When the
-point-at location points to a declaration with a Doxygen-style
comment, the indexer testbed prints the associated comment
block(s). See test/Index/comments.c for an example.
Some notes:
- We don't actually attempt to parse the comment blocks themselves,
beyond identifying them as Doxygen comment blocks to associate them
with a declaration.
- We won't find comment blocks that aren't adjacent to the
declaration, because we start our search based on the location of
the declaration.
- We don't go through the necessary hops to find, for example,
whether some redeclaration of a declaration has comments when our
current declaration does not. Similarly, we don't attempt to
associate a \param Foo marker in a function body comment with the
parameter named Foo (although that is certainly possible).
- Verification of my "no performance impact" claims is still "to be
done".

Lazy deserialization of the declaration chains associated with
identifiers from a precompiled header.
This patch changes the primary name lookup method for entities within
a precompiled header. Previously, we would load all of the names of
declarations at translation unit scope into a large DenseMap (inside
the TranslationUnitDecl's DeclContext), and then perform a special
"last resort" lookup into this DeclContext when we knew there was a
PCH file (see Sema::LookupName). Now, when we see an identifier named
for the first time, we load all of the declarations with that name
that are visible from the translation unit into the IdentifierInfo's
chain of declarations. Thus, the explicit "look into the translation
unit's DeclContext" code is gone, and Sema effectively uses the same
IdentifierInfo-based name lookup mechanism whether we are using a PCH
file or not.
This approach should help PCH scale with the size of the input program
rather than the size of the PCH file. The "Hello, World!" application
with Carbon.h as a PCH file now loads 20% of the identifiers in the
PCH file rather than 85% of the identifiers.
90% of the 20% of identifiers loaded are actually loaded when we
deserialize the preprocessor state. The next step is to make the
preprocessor load macros lazily, which should drastically reduce the
number of types, declarations, and identifiers loaded for "Hello,
World".

Lazy deserialization of function bodies for PCH files. For the Carbon
"Hello, World!", this takes us from deserializing 6469
statements/expressions down to deserializing 1
statement/expression. It only translated into a 1% improvement on the
Carbon-prefixed 403.gcc, but (a) it's the right thing to do, and (b)
we expect this to matter more once we lazily deserialize identifiers.

FunctionDecl::getBody() is getting an ASTContext argument for use in
lazy PCH deserialization. Propagate that argument wherever it needs to
be. No functionality change, except that I've tightened up a few PCH
tests in preparation.

When writing a PCH file, keep track of all of the non-static,
non-inline external definitions (and tentative definitions) that are
found at the top level. The corresponding declarations are stored in a
record in the PCH file, so that they can be provided to the
ASTConsumer (via HandleTopLevelDecl) when the PCH file is read.

Various minor fixes to PCH reading and writing, with general
cleanup. Aside from a minor tweak to the PCH file format, no
functionality change.

Implementation of pre-compiled headers (PCH) based on lazy
de-serialization of abstract syntax trees.
PCH support serializes the contents of the abstract syntax tree (AST)
to a bitstream. When the PCH file is read, declarations are serialized
as-needed. For example, a declaration of a variable "x" will be
deserialized only when its VarDecl can be found by a client, e.g.,
based on name lookup for "x" or traversing the entire contents of the
owner of "x".
This commit provides the framework for serialization and (lazy)
deserialization, along with support for variable and typedef
declarations (along with several kinds of types). More
declarations/types, along with important auxiliary structures (source
manager, preprocessor, etc.), will follow.
