(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.

Baby steps towards migrating the InitListChecker over to the new initialization code. Pass an InitializedEntity pointer through to most init checker functions. Right now, it's ignored everywhere except when initializing vectors in C++.

incomplete type (or a pointer/reference to such).

The causes of this problem are different enough to justify a different "design"
for the diagnostic.  Most notably, it doesn't give an operand index:
it's usually pretty obvious which operand is the problem, it adds a lot of
clutter to mention it, and the fix is usually in a different part of the file
anyway.

This is yet another diagnostic that should really have an analogue in the
non-overloaded case --- which should be much easier to write because of
the weaker space constraints.

Fix the EntityKind order so that all entity kinds that can be copied (using copy constructors) come first. Also, fix a bug where EK_New was left out of the err_init_conversion_failed diagnostic (It is now reported as 'new value'). Please review Doug :)

conversions.  To make this work, fill out all conversions for all candidates
(but only when diagnosing overload failure).  Split out a few cases from
ovl_fail_bad_conversion which didn't actually involve a failed argument
conversion.

I'm pretty sure this is not a well-founded ordering, but I'm not sure it matters.

Separate EK_ArrayOrVectorElement into EK_ArrayElement and EK_VectorElement; arrays and vectors are pretty different beasts in C++. Doug, please review/comment.

Add 'clang_getClangVersion()' function to CIndex.  This exposes the full Clang version string through the CIndex API.

Move version string generation (e.g., "clang 1.1 ...") to libBasic/Version.cpp, getClangFullVendorVersion().

    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...

of this traversal rather than using the Index library; the unified
cursor visitor is more complete, and will be The Way Forward.

Minor other tweaks needed to make this work:
  - Extend Preprocessor::getLocForEndOfToken() to accept an offset
  from the end, making it easy to move to the last character in the
  token (rather than just past the end of the token).
  - In Lexer::MeasureTokenLength(), the length of whitespace is zero.
