A small fix for the aspect Yield defined in AI12-0279 for Ada 2022, to
accept aspect given for a subprogram body which acts as its own spec.
For example:
procedure Switch with Yield => True is
begin
...
end Switch;
Tested on x86_64-pc-linux-gnu, committed on trunk
gcc/ada/
* sem_ch13.adb (Analyze_Aspect_Yield): Look at the entity kind,
not at the declaration kind.
