* [MachineLICM] Debug intrinsics shouldn't affect hoist decisionsGeoff Berry2018-05-041-0/+32
Summary: When checking if an instruction stores to a given frame index, check that the instruction can write to memory before looking at the memory operands list to avoid e.g. DBG_VALUE instructions that reference a frame index preventing a load from that index from being hoisted.
