This patch is by Simone Atzeni with portions by Adhemerval Zanella. This contains the LLVM patches to enable the thread sanitizer for PPC64, both big- and little-endian. Two different virtual memory sizes are supported: Old kernels use a 44-bit address space, while newer kernels require a 46-bit address space. There are two companion patches that will be added shortly. There is a Clang patch to actually turn on the use of the thread sanitizer for PPC64. There is also a patch that I wrote to provide interceptor support for setjmp/longjmp on PPC64. Patch discussion at reviews.llvm.org/D12841. llvm-svn: 255057
