SanitizerArgs: add ability to filter/diagnose unsupported sanitizers. The thread, memory, dataflow and function sanitizers are now diagnosed if enabled explicitly on an unsupported platform. Unsupported sanitizers which are enabled implicitly (as part of a larger group) are silently disabled. As a side effect, this makes SanitizerArgs parsing toolchain-dependent (and thus essentially reverts r188058), and moves SanitizerArgs ownership to ToolChain.

// Verify that -fsanitize=thread invokes tsan instrumentation.
Add a flag -fthread-sanitizer. This flag enables ThreadSanitizer instrumentation committed to llvm as r150423. The patch includes one test for -fthread-sanitizer and one similar test for -faddress-sanitizer. This patch does not modify the linker flags (as we do it for -faddress-sanitizer) because the run-time library is not yet committed and it's structure in compiler-rt is not 100% clear. The users manual wil be changed in a separate commit. llvm-svn: 151846
