faster hashing may help, but I think the intention of the patch is to eliminate unnecessary computation completely.
================
Comment at: llvm/include/llvm/ProfileData/SampleProf.h:635
+ // consistent with the profile map's key.
+ // If non-context function is already MD5 string, do not hash again.
+ uint64_t Hash;
----------------
how often is the name already MD5 string?
