Tom Stellard cc0bc941d4 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.
