[GlobalISel][Legalizer] Fix minScalarEltSameAsIf to handle p0 element types.

The mutation the action generates tries to change the input type into the
element type of larger vector type. This doesn't work if the larger element
type is a vector of pointers since it creates an illegal mutation between
scalar and pointer types.
