[analyzer] Refactoring: Move checkers into lib/GR/Checkers and their own library, libclangGRCheckers

Don't warn about unamed bitfield ivars in the ObjCUnusedIvarsChecker.  Fixes <rdar://problem/8481311>.

Add raw_ostream operators to NamedDecl for convenience. Switch over all users of getNameAsString on a stream.

The next step is to print the name directly into the stream, avoiding a temporary std::string copy.

when it is explicitly marked as unused via __attribute__((unused)).

(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.

Unused ivar checker: ivars referenced by lexically nested functions should not be flagged as unused.  Fixes <rdar://problem/7254495>.

Unused ivars checker: also check methods in categories that are defined in the same translation unit.  Fixes <rdar://problem/6260004>.

AnalysisContext should never change. Along the way, propagate some constness
around.

Remove ASTContext parameter from DeclContext's methods. This change cascaded down to other Decl's methods and changes to call sites started "escalating".
Timings using pre-tokenized "cocoa.h" showed only a ~1% increase in time run between and after this commit.

llvm-svn: 74506

Timings showed no significant difference before and after the commit.

llvm-svn: 74504

The implementations of these methods can Use Decl::getASTContext() to get the ASTContext.

This commit touches a lot of files since call sites for these methods are everywhere.
I used pre-tokenized "carbon.h" and "cocoa.h" headers to do some timings, and there was no real time difference between before the commit and after it.

methods, class methods, and property implementations) and instead
place all of these entities into the DeclContext.

This eliminates more linear walks when looking for class or instance
methods and should make PCH (de-)serialization of ObjCDecls trivial
(and lazy).

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.

uses of getName() with uses of getDeclName().  This upgrades a bunch of
diags to take DeclNames instead of std::strings.

This also tweaks a couple of diagnostics to be cleaner and changes
CheckInitializerTypes/PerformInitializationByConstructor to pass
around DeclarationNames instead of std::strings.

Refine the error message of unused ivars.
Added test case.
