f7228f7038 Fix Windows build, don't try to #include <pthread.h> when we know it's not 
available.

4d0a9ff365 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!

13b10731ab Implement comparison operators for BranchProbability in a way that can't overflow INT64_MAX. 
Add a test case for the edge case that triggers this. Thanks to Chandler for bringing this to my attention.

f56dc281ce NULL cannot be portably used as the last argument to a function with __attribute((sentinel)), even though it usually works. Use (void*)0 instead. PR11002.

4bffb62289 unittests/Support/DataExtractorTest.cpp: Specify ULL explicitly to a few constants.

8c74f7f299 Add the DataExtractor utility class. 
It is an endian-aware helper that can read data from a StringRef. It will
come in handy for DWARF parsing. This class is inspired by LLDB's
DataExtractor, but is stripped down to the bare minimum needed for DWARF.

Comes with unit tests!
