Matt Arsenault d40e1c3fbc Add triple to test to fix bots

Matt Arsenault 8239eaab99 Add DAG combine for shl + add of constants. 
Do
 (shl (add x, c1), c2) -> (add (shl x, c2), c1 << c2)

This is already done for multiplies, but since multiplies
by powers of two are turned into shifts, we also need
to handle it here.

This might want checks for isLegalAddImmediate to avoid
transforming an add of a legal immediate with one that isn't.
