[LLVMdev] compiler-rt tests in cmake?

[Sergey Matveev]

As a temporary fix, you can replace this line in sanitizer_linux_libcdep.c:

const uptr kThreadDescriptorSize = FIRST_32_SECOND_64(1216, 2304);

with

const uptr kThreadDescriptorSize = FIRST_32_SECOND_64(1168, 2304);

The tests should pass after that. I need to figure out which ifdefs to put
this under, so I might not be able to land the fix until Monday.
