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.
