[Ada] Fix check for looking for user defined literals
Recall that Has_Possible_Literal_Aspects only comes in if a given node
does not have any visible interpretation. If one operand is a literal we
assume that there may be a user-defined literal defined for some type to
be determined during the downward pass of resolution, but that depends
on the existence of some user-defined function or operator that can take
that literal as an actual. If analysis did not find such, the call is
illegal. I think that the following must be added to Operator_Check to
recover the proper error.
Note that this breaks current partial implementation of user-defined
literals.
