ada: Spurious error on Lock_Free protected type with discriminants
This patch corrects an issue in the compiler whereby unprefixed discriminants
appearing in protected subprograms were unable to be properly resolved -
leading to spurious resolution errors.
gcc/ada/
* sem_ch8.adb (Set_Entity_Or_Discriminal): Verify we are actually
resetting the entity field of a non-prefixed discriminant
reference.
