This corresponds to a fix in llvm::SplitBlockAndInsertIfThen.

[sanitizer] deadlock detector: a) initial support for suppressions, b) be more robust in case we failed to extract a stack trace for one of the locks

llvm-svn: 204225

llvm-svn: 204182

Compiler-rt part of MSan implementation of advanced origin tracking,
when we record not only creation point, but all locations where
an uninitialized value was stored to memory, too.

[sanitizer] reverse the order of the stack traces printed for every pair of locks in the deadlock report (first print the 'from' node, then print the 'to' node of the deadlock graph)

llvm-svn: 204043

[sanitizer] make the deadlock detector print 2*N stack traces on lock-order-inversion with N locks (i.e. print stack traces for both lock acquisitions in every edge in the graph). More improvements to follow

if the thread is cancelled in pthread_cond_wait, it locks the mutex before
processing pthread_cleanup stack
but tsan was missing that, thus reporting false double-lock/wrong-unlock errors
see the test for details

Summary:
We don't need to do any work in this case - just take
the current PC and caller PC.
