[PATCH] D70286: Merge memtag instructions with adjacent stack slots.

Ping.

Most of the smaller changes in this patch (almost everything outside of AArch64FrameLowering.cpp) are needed to handle FrameIndex operand in STGloop. It is so special because STGloop has a writeback constraint, which regalloc has no way of honoring in the case when the input operand is FrameIndex; therefore eliminateFrameIndex has to be smart about the choice of the scratch register there.
