Derek Schuff 6435e10dbd Factor PrologEpilogInserter around spilling, frame finalization, and scavenging ... PrologEpilogInserter has these 3 phases, which are related, but not all of them are needed by all targets. This patch reorganizes PEI's varous functions around those phases for more clear separation. It also introduces a new TargetMachine hook, usesPhysRegsForPEI, which is true for non-virtual targets. When it is true, all the phases operate as before, and PEI requires the AllVRegsAllocated property on MachineFunctions. Otherwise, CSR spilling and scavenging are skipped and only prolog/epilog insertion/frame finalization is done.
