mem-mem moves.
The following patch is Shiva Chen's patch to fix a LRA bug on some
experimental target. The bug occurs when one insn requires many reloads
and they are done on different passes. I evaluate the probability of
this bug for other targets as quite tiny.
The patch was approved by me.
Success
