Craig Topper 8917647333 [InstCombine] Pull shifts through a select plus binop with constant 
This pulls shifts through a select+binop with a constant where the select conditionally executes the binop. We already do this for just the binop, but not with the select.

This can allow us to get the select closer to other selects to enable removing one.
