expressions. This is mostly a simple refact, splitting the main "start
a lambda expression" function into smaller chunks that are driven
either from the parser (Sema::ActOnLambdaExpr) or during AST
transformation (TreeTransform::TransformLambdaExpr). A few minor
interesting points:
- Added new entry points for TreeTransform, so that we can
explicitly establish the link between the lambda closure type in the
template and the lambda closure type in the instantiation.
- Added a bit into LambdaExpr specifying whether it had an explicit
result type or not. We should have had this anyway.
This code is 'lightly' tested.

This is useful for clients that want to maintain compatibility
across multiple releases of LLVM. Currently users like Klee and
Mesa all have to roll their own 'parse llvm-config --version
output and generate defines' solution.
Also reuse the new macros so that version information is less
redundant/likely to fall out of sync again in the future.

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.

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().
