[GlobalISel] Implement commuting shl (add/or x, c1), c2 -> add/or (shl x, c2), c1 << c2
There's a target hook that's called in DAGCombiner that we stub here, I'll
implement the equivalent override for AArch64 in a subsequent patch since it's
used by different shift combine.
This change by itself has minor code size improvements on arm64 -Os CTMark:
