[IndVarSimplify] Forget phi value after changing incoming value.
This fixes an issue exposed by D71539, where IndVarSimplify tries
to access an invalid cached SCEV expression after making changes to the
underlying PHI instruction earlier.

When changing the incoming value of a PHI, forget the cached SCEV for
the PHI.
