Detailed Description

Post-legalization lowering for instructions.

This is used to offload pattern matching from the selector.

For example, this combiner will notice that a G_SHUFFLE_VECTOR is actually a G_ZIP, G_UZP, etc.

General optimization combines should be handled by either the AArch64PostLegalizerCombiner or the AArch64PreLegalizerCombiner.
