Evgeniy Stepanov f7f616ba66 Quick fix data/bss detection in TSan. 
The old way breaks when a module's bss is adjacent to the [heap] vm area.
Both ways are not very reliable, though.

Alexey Samsonov a555b3faf4 [ASan] Apply some ASan-relevant pieces of patch by Ruben Van Boxem. In the same time, remove ASan from CMake build on Windows after conversation with Timur. We don't want to support building ASan on Windows until it is in a working state.

Michael J. Spencer c774095d44 [CMake][tsan] Compile .S files for tsan as C instead of CXX. 
Using CXX breaks if you add -stdlib=libc++ to CMAKE_CXX_FLAGS.

Alexey Samsonov 341e5bcb45 [TSan] port all output tests to lit and move them to lit_tests directory. This makes 'make check-tsan' command test both unit and output TSan tests. Old custom makefiles for running TSan tests are still functional as well.

Bill Wendling 66429fe1c7 Add support for reading the GCDA file and merging the arc information. 
With the advent of the __llvm_gcov_flush function, we need to be able to merge
counts into the .gcda files in an intelligent manner. This involves reading the
file if it exists, adding the counts together, and then writing the results.
