389fa6c38d Silence tsan false-positives (tsan can't track things which are only safe due to 
memory fences) in statistics registration, which works the same way that
ManagedStatic registration does.

b92661d00a [Win32] Catch exceptions (eg. segfault) on waiting for invoked clang from the driver. 
clang/lib/Driver/Driver.cpp: Don't pass through negative exit status, or parent would be confused.

llvm::sys::Program::Wait(): Suppose 0x8000XXXX and 0xC000XXXX as abnormal exit code and pass it as negative value.

Win32 Exception Handler: Exit with ExceptionCode on an unhandle exception.

9751c17d0d rename ENABLE_THREADS to LLVM_ENABLE_THREADS 
Now that it needs to be exported in a public header (Valgrind.h)
it should be prefixed to avoid collision with other projects.
Add it to llvm-config.h as well.

This'll require regenerating the configure script after this
commit, but I don't have the required autoconf version.

448be745f6 Fix APFloat::convert so that it handles narrowing conversions correctly; it 
was returning incorrect values in rare cases, and incorrectly marking
exact conversions as inexact in some more common cases. Fixes PR11406, and a
missed optimization in test/CodeGen/X86/fp-stack-O0.ll.

de9c504d6b Turn error recovery into an assert. 
This was put in because in a certain version of DragonFlyBSD stat(2) lied about the
size of some files. This was fixed a long time ago so we can remove the workaround.

53185e9016 Add support for tsan annotations (thread sanitizer, a valgrind-based tool). 
These annotations are disabled entirely when either ENABLE_THREADS is off, or
building a release build. When enabled, they add calls to functions with no
statements to ManagedStatic's getters.

Use these annotations to inform tsan that the race used inside ManagedStatic
initialization is actually benign. Thanks to Kostya Serebryany for helping
write this patch!
