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".

Shifter ops are not always free. Do not fold them (especially to form
...
complex load / store addressing mode) when they have higher cost and
when they have more than one use.
