AMDGPU/LoadStoreOptimizer: combine MMOs when merging instructions
Summary:
The LoadStoreOptimizer was creating instructions with 2
MachineMemOperands, which meant they were assumed to alias with all other instructions,
because MachineInstr:mayAlias() returns true when an instruction has multiple
MachineMemOperands.
This was preventing these instructions from being merged again, and was
giving the scheduler less freedom to reorder them.
