[ASan] Do not instrument other runtime functions with `__asan_handle_no_return`

Summary:
Currently, ASan inserts a call to `__asan_handle_no_return` before every
`noreturn` function call/invoke. This is unnecessary for calls to other
runtime funtions. This patch changes ASan to skip instrumentation for
functions calls marked with `!nosanitize` metadata.
