Change @llvm.clear_cache default to call rt-lib

Description

Change @llvm.clear_cache default to call rt-lib

After some discussion on IRC, emitting a call to the library function seems
like a better default, since it will move from a compiler internal error to
a linker error, that the user can work around until LLVM is fixed.

I'm also adding a note on the responsibility of the user to confirm that
the cache was cleared on platforms where nothing is done.
