rs6000: Unify error messages for built-in constant restrictions

rs6000: Unify error messages for built-in constant restrictions

We currently give different error messages for built-in functions that
violate range restrictions on their arguments, depending on whether we
record them as requiring an n-bit literal or a literal between two values.
It's better to be consistent.  Change the error message for the n-bit
literal to look like the other one.
