Split libAnalysis into two libraries: libAnalysis and libChecker.
(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.

ASTUnit: Don't check that input files exist when parsing ASTs from the command
line -- they may be remapped (fake) files. This is useful for testing parsing
entirely from memory.

CIndex: Don't crash when visitor passes null child statements, and sprinkle some
asserts in cursor construction functions to make this more obvious.
Doug, please check. c-index-test would previously crash on this code:
--
for(;;) {}

Do we need a custom visit of the for statement to cover the variable
declarations?

Fix a pretty bad bug where if a constructor (or conversion function) was marked as 'explicit', but then defined out-of-line, we would not treat it as being explicit.

substantial updating to match recent CIndex API changes.

add a prototype for __builtin_fpclassify. We don't know how to
codegen it, so we get 'cannot compile this builtin function yet'
errors, just like we do currently for __builtin_isinf. However,
this should let us parse headers that use it without barfing,
which should help PR6083.

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++.

Produce a special diagnostic when users call a function with an argument of
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 :)

During overload resolution diagnostics, sort non-viable candidates by the quality of their
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.

(1) Rename getClangSubversionRevision() to getClangRevision(), and
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...

Teach CIndex's cursor visitor to restrict its traversal to a specific
region of interest (if provided). Implement clang_getCursor() in terms
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.

No need to canonicalize the type and use dyn_cast. Also, correctly diagnose trying to override a function returning an lvalue reference with a function overriding an rvalue reference.
