[Ada] Fix resolution of class-wide operations that are generic actuals
2018-07-31 Ed Schonberg <schonberg@adacore.com>
gcc/ada/
* sem_ch4.adb (Traverse_Homonyms): Consider generic actuals that
may rename a matching class-wide operation only if the renaming
declaration for that actual is in an enclosing scope (i.e.
within the corrresponding instance).
