so that CIndex can report diagnostics through the normal mechanisms
even when executing Clang in a separate process. This applies both
when performing code completion and when using ASTs as an intermediary
for clang_createTranslationUnitFromSourceFile().
The serialized format is not perfect at the moment, because it does
not encapsulate macro-instantiation information. Instead, it maps all
source locations back to the instantiation location. However, it does
maintain source-range and fix-it information. To get perfect fidelity
from the serialized format would require serializing a large chunk of
the source manager; at present, it isn't clear if this code will live
long enough for that to matter.

(1) libAnalysis is a generic analysis library that can be used by
Sema. It defines the CFG, basic dataflow analysis primitives, and
inexpensive flow-sensitive analyses (e.g. LiveVariables).
(2) libChecker contains the guts of the static analyzer, incuding the
path-sensitive analysis engine and domain-specific checks.
Now any clients that want to use the frontend to build their own tools
don't need to link in the entire static analyzer.
This change exposes various obvious cleanups that can be made to the
layout of files and headers in libChecker. More changes pending. :)
This change also exposed a layering violation between AnalysisContext
and MemRegion. BlockInvocationContext shouldn't explicitly know about
BlockDataRegions. For now I've removed the BlockDataRegion* from
BlockInvocationContext (removing context-sensitivity; although this
wasn't used yet). We need to have a better way to extend
BlockInvocationContext (and any LocationContext) to add
context-sensitivty.

have it return a StringRef instead of an integer (to be more VCS
agnostic).
(2) Add getClangFullRepositoryVersion(), which contains an
amalgamation of the repository name and the revision.
(3) Change PCH to only emit the string returned by
getClangFullRepositoryVersion() instead of also emitting the value
of getClangSubversionRevision() (which has been removed). This is
functionally equivalent.
More cleanup to version string generation pending...

previously only had a single location (the @ in @interface); now we
know where the @ is (for the start of the declaration), where the
class name is (that's the normal "location" now for diagnostics), and
where the category name is. Also, eliminated the redundant "end"
location, since ObjCContainerDecl already has better @end information.
The only XFAIL'd test is temporary; will un-XFAIL-it once I've taught
CIndex how to use the new locations.

Objective-C classes, protocol definitions, forward protocol
declarations, and categories. This information isn't actually used
yet; that's coming next.

clang -cc1 logic for running an action against a set of options.
- This should make it easier to build tools that have a clang -cc1 like
interface, but aren't actually part of clang -cc1.

1. Add helper class for sema checks for target attributes
2. Add helper class for codegen of target attributes
As a proof-of-concept - implement msp430's 'interrupt' attribute.

std::vectors.
- MacroBuilder wraps a raw_ostream so it can easily write to any buffer
supported by raw_ostream.
- MacroBuilder's method take Twines for easy string concatenation (this was done
with sprintf and temporary buffers before).
- Targets still use std::vector as they don't have access to the builder.

piece of the declaration. The '@' and the 'end' are separate tokens,
and require two SourceLocations to accurately track.
This change was motivated because ObjCContainerDecl::getSourceRange()
would previously not return the entire range of the declaration (the
'end' would be left off).

corresponding @interface, provide a note showing which interface we're
referring to. This note has the fix-it hint on it.
Also, don't automatically apply fix-it hints for notes. They're meant
to express fix-its that would change semantics.

This fix was dropped when I integrated the 'objective-rewrite' branch.

GRStateManager. Having these references was an abstraction violation,
as they really should only be known about GRExprEngine.
This change required adding a new 'ProcessAssume' callback in
GRSubEngine. GRExprEngine implements this callback by calling
'EvalAssume' on all registered Checker objects as well as the
registered GRTransferFunc object.

code-completion with macro names behaves the same with or without

Add new states for symbolic regions tracked by malloc checker. This enables us
to do malloc checking more accurately. See test case.
Based on Lei Zhang's patch and discussion.
