The memprof profiles and binaries need to be updated in case of version updates. This change adds three scripts for llvm-profdata, clang and llvm tests where memprof profiles are used as inputs. Also update the tests, profiles and binaries in this change. Change based on the review suggestions in D145023. Reviewed By: tejohnson Differential Revision: https://reviews.llvm.org/D145644
