powerpc: enable supported sanitizers on powerpc64*
1. Merge LLVM's 315d792130258a9b7250494be8d002ebb427b08f, adding support for FreeBSD/powerpc64*. 2. Add sanitizer list to lib/libclang_rt/Makefile, taken from the list of libraries that llvm-devel port builds. 3. powerpc64le supports the same sanitizers that powerpc64, but powerpc64le also supports xray* sanitizers. 4. lib/libclang_rt/xray/Makefile hardcodes amd64-specific files, so that needs to be conditionalized. 5. Sanitizers are not enabled for powerpc, because powerpc supports only builtins and profile. Reviewed by: dim Differential Revision: https://reviews.freebsd.org/D35228 Relnotes: yes MFC after: 3 days
