[SystemZ] Rename mapping table fields
Rename Function->DispKey and PairType->DispSize. I'd originally used "Function" because I thought it might be useful for other InstMappings. However, it turns out that having two very similar instructions with the same Function makes it pretty useless for anything other than the displacement size key. Other InstMappings will want the key to be defined for only one instruction in the pair. No behavioural change intended. llvm-svn: 185526
