Nick Desaulniers	a63d4f6cba	[Clang][Codegen] rename no_profile fn attr no_profile_instrument_function ... GCC has had this function attribute since GCC 7.1 for this purpose. I added "no_profile" last week in D104475; rename this to "no_profile_instrument_function" to improve compatibility with GCC.

Nick Desaulniers	193e41c987	[Clang][Codegen] Add GNU function attribute 'no_profile' and lower it to noprofile ... noprofile IR attribute already exists to prevent profiling with PGO; emit that when a function uses the newly added no_profile function attribute. The Linux kernel would like to avoid compiler generated code in functions annotated with such attribute. We already respect this for libcalls to fentry() and mcount().
