Do type conversion to match columns in UNION clauses.
Currently force the type to match the _first_ select in the union. Move oper_select_candidate() from parse_func.c to parse_oper.c. Throw error inside of oper_inexact() if no match for binary operators. Check more carefully that types can be coerced even if there is only one candidate operator in oper_inexact(). Fix up error messages for more uniform look. Remove unused code. Fix up comments.
