(Eval_Arithmetic_Op, Eval_Relational_Op, Eval_Unary_Op):
Use the above to identify the operand type so it can be properly frozen.
* sem_res.adb (Make_Call_Into_Operator): Remove bogus freeze of operand
type, done in an arbitrary, possibly incorrect type (the presence of
some numeric type in the scope is checked for legality, but when more
than one such type is in the scope, we just pick a random one, not
necessarily the expected one).
* sem_utils.ads, sem_utils.adb (Is_Universal_Numeric_Type): New utility
subprogram.
