[MSan] add KMSAN support to Clang driver
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.
