Pool-allocation for MachineInstrs, MachineBasicBlocks, and

This drastically reduces the number of calls to malloc/free made

in CodeGen. Combined with other changes, this speeds up the
"instruction selection" phase of CodeGen by 10% in some cases.

hook for each way in which a result type can be

just use one: ReplaceNodeResults, which returns
