[PATCH] D47690: [X86][BMI][TBM] Only demand bottom 16-bits of the BEXTR control op (PR34042)

It fails on trunk. Your patch probably fixes it by shrinking the immediate. Is there anything that can prevent the DAG combine from running that we should be concerned about? If there is we might not need to clamp the immediate in lowering or isel.
