This commit contains the trivial portion of the port of ASan to
Myriad RTEMS.

- Whitelist platform in sanitizer_platform.h, ubsan_platform.h
- Turn off general interception
- Enable memintrinsics interception
- Use memset for FastPoisonShadow
- Define interception wrappers
- Set errno symbol correctly
- Enable ASAN_LOW_MEMORY
- Enable preinit array
- Disable slow unwinding
- Use fuchsia offline symbolizer
- Disable common code for: InitializeShadowMemory, CreateMainThread, AsanThread::ThreadStart, StartReportDeadlySignal, MaybeReportNonExecRegion.
- Also include a header asan_interceptors_memintrinsics.cc so that it compiles for RTEMS.
