Detailed Description

Post-legalization combines on generic MachineInstrs.

The combines here must preserve instruction legality.

Lowering combines (e.g. pseudo matching) should be handled by AArch64PostLegalizerLowering.

Combines which don't rely on instruction legality should go in the AArch64PreLegalizerCombiner.
