Boilerplate code for using KMSAN instrumentation in Clang. We add a new command line flag, -fsanitize=kernel-memory, with a corresponding SanitizerKind::KernelMemory, which, along with SanitizerKind::Memory, maps to the memory_sanitizer feature. KMSAN is only supported on x86_64 Linux. It's incompatible with other sanitizers, but supports code coverage instrumentation. llvm-svn: 341641
