Re-commit 117518 and 117519 now that ARM MC test failures are out of the way.

Revert 117518 and 117519 for now. They changed scheduling and cause MC tests to fail. Ugh.

- Assign load / store with shifter op address modes the right itinerary classes.
...
- For now, loads of [r, r] addressing mode is the same as the
[r, r lsl/lsr/asr #] variants. ARMBaseInstrInfo::getOperandLatency() should
identify the former case and reduce the output latency by 1.
- Also identify [r, r << 2] case. This special form of shifter addressing mode
is "free".

Change ARM scheduling default to list-hybrid if the target supports floating point instructions (and is not using soft float).
