The generic BaseMemOpClusterMutation calls into TargetInstrInfo to analyze the address of each load/store instruction, and again to decide whether two instructions should be clustered. Previously this had to represent each address as a single base operand plus a constant byte offset. This patch extends it to support any number of base operands. The old target hook getMemOperandWithOffset is now a convenience function for callers that are only prepared to handle a single base operand. It calls the new more general target hook getMemOperandsWithOffset. The only requirements for the base operands returned by getMemOperandsWithOffset are: - they can be sorted by MemOpInfo::Compare, such that clusterable ops get sorted next to each other, and - shouldClusterMemOps knows what they mean. One simple follow-on is to enable clustering of AMDGPU FLAT instructions with both vaddr and saddr (base register + offset register). I've left a FIXME in the code for this case.
