[cfe-commits] [PATCH] Various minor bug fixes to thread-safety analysis.

[Delesley Hutchins]

This patch fixes several bugs in the recently-added thread safety
analysis, so that clang can be used to build itself with either
-Wthread-safety or -Weverything enabled.  This patch has been code
reviewed by Chandler Carruth and Jeffrey Yasskin; prior comments can
be found at:

I have added regression tests for the troublesome cases to
test/SemaCXX/warn-thread-safety-parsing.cpp.  Note that in two cases,
there may be a possible bug in the clang AST.  I have marked these two
cases with a FIXME comment in the patch -- perhaps someone with
greater knowledge in this area can let me know if I have encountered a
bug or if the behavior is expected.
