Fix unaligned memory read issue exposed by ubsan Indexed profile data as designed today does not guarantee counter data to be well aligned, so reading needs to use the slower form (with memcpy). This is less than ideal and should be improved in the future (i.e., with fixed length function key instead of variable length name key). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@253309 91177308-0d34-0410-b5e6-96231b3b80d8
