DeLesley Hutchins e2a3f75a12 Thread safety analysis: expand set of expressions that can be used to denote locks.

Richard Smith bc638767f8 Reinstate r151879, r151880, reverted in r151922, along with a bugfix for
scalar emission of DeclRefExprs to const bools: emit scalar bools as i1,
not as i8.

In addition to the extra unit testing, this has successfully bootstrapped.

Anna Zaks fc5dfe9f7c [analyzer] Rename clang::CallGraph into clang::idx::CallGraph + rename
the corresponding files to avoid confusion.

This is a preparation to adding an AST-based call graph to Analysis. The
existing call graph works with indexer entries. We might be able to
refactor it to use the AST based graph in the future.

(Minimal testing here as the only example that uses the API has been
completely broken, does not compile.)

The patch includes one test for -fthread-sanitizer and one similar test for -faddress-sanitizer.
This patch does not modify the linker flags (as we do it for -faddress-sanitizer) because the run-time library is not yet
committed and it's structure in compiler-rt is not 100% clear.

Eli Friedman 98b01edc8c Implement "optimization" for lambda-to-block conversion which inlines the generated block literal for lambdas which are immediately converted to block pointer type. This simplifies the AST, avoids an unnecessary copy of the lambda and makes it much easier to avoid copying the result onto the heap.
Note that this transformation has a substantial semantic effect outside of ARC: it gives the converted lambda lifetime semantics similar to a block literal.  With ARC, the effect is much less obvious because the lifetime of blocks is already managed.

[libclang] When indexing @synthesized objc methods, report the @implementation
as the lexical container.
