[CodeGenPrepare][NFC] Rename TargetTransformInfo::expandMemCmp -> TargetTransformInfo::enableMemCmpExpansion.

Summary:
Right now there are two functions with the same name, one does the work
and the other one returns true if expansion is needed. Rename
TargetTransformInfo::expandMemCmp to make it more consistent with other
members of TargetTransformInfo.

Remove the unused Instruction* parameter.
