[PATCH][AArch64] Stop redundant zero-extension after UMOV when in DI mode
This patch extends the aarch64_get_lane_zero_extendsi instruction
definition to also cover DI mode. This prevents a redundant AND
instruction from being generated due to the pattern failing to be matched.
Committed on behalf of Sam Tebbs.
