Currently, loading from or storing to a stack location with a structured load or store crashes in isAArch64FrameOffsetLegal as the opcodes are not handled by getMemOpInfo. This patch adds the opcodes for structured load/store instructions with an immediate index to getMemOpInfo & getLoadStoreImmIdx, setting appropriate values for the scale, width & min/max offsets.
