1) Support the case when realloc fails to reduce False Positives. (We
essentially need to restore the state of the pointer being reallocated.)

2) Realloc behaves differently under special conditions (from pointer is
null, size is 0). When detecting these cases, we should consider
under-constrained states (size might or might not be 0). The
old version handled this in a very hacky way. The code did not
differentiate between definite and possible (no consideration for
under-constrained states). Further, after processing each special case,
the realloc processing function did not return but chained to the next
special case processing. So you could end up in an execution in which
you first see the states in which size is 0 and realloc ~ free(),
followed by the states corresponding to size is not 0 followed by the
evaluation of the regular realloc behavior.

CXXRecordDecl in a way that actually makes some sense:
  - LambdaExpr contains all of the information for initializing the
  lambda object, including the capture initializers and associated
  array index variables.
  - CXXRecordDecl's LambdaDefinitionData contains the captures, which
  are needed to understand the captured variable references in the
  body of the lambda.

LambdaExpr over to the CXXRecordDecl. This allows us to eliminate the
back-link from the closure type to the LambdaExpr, which will simplify
and lazify AST deserialization.

This should help to detect problems with ASLR or linker tricks early.

Fix build breakage from r150378: MSVC only allows taking the
address of a member function using the &ClassName::Function
syntax.# It was giving

This was never being compiled at all and was bitrotting
as a result.

Also compile SampleAnalyzerPlugin as a module, not a library,
and fix a mistake with not passing the source files
to add_clang_library().

- Use unsigned literals when the desired result is unsigned. This mostly allows unsigned/signed mismatch warnings to be less noisy even if they aren't on by default.
- Remove misplaced llvm_unreachable.
- Add static to a declaration of a function on MSVC x86 only.
- Change some instances of calling a static function through a variable to simply calling that function while removing the unused variable.
