In D152577 <https://reviews.llvm.org/D152577> @xur has a post-submit comment regarding to an awkward usage of MFS for Autofdo - instead of just using -fsplit-machine-function, the user needs to add "-mllvm -mfs-psi-cutoff=0" to choose the right logic for AutoFDO. The compiler should choose the right default values for such case.

This CL separate MFS logic for different profile types.
