Cleanup ImmToIdxMap and noImmForm in PPCRegisterInfo
ImmToIdxMap should be a DenseMap (not a std::map) because there
is no ordering requirement. Also, we don't need a separate list
of instructions for noImmForm in eliminateFrameIndex, because this
list is essentially the complement of the keys in ImmToIdxMap.
No functionality change intended.
