[Ada] Crash in task body reference to discriminant
The compiler may crash processing the successor or predecessor of a task
type discrete discriminant.
gcc/ada/
* sem_attr.adb (Resolve_Attribute): Ensure that attribute
expressions are resolved at this stage; required for preanalyzed
references to discriminants since their resolution (and
expansion) will take care of updating their Entity attribute to
reference their discriminal.
