* sem_ch4.adb (Analyze_Expression_With_Actions.Check_Action_Ok):
Accept an executable pragma occuring in a declare expression as
per AI22-0045. This means Assert and Inspection_Point pragmas as
well as any implementation-defined pragmas that the implementation
chooses to categorize as executable. Currently Assume and Debug
are the only such pragmas.
Tested on x86_64-pc-linux-gnu, committed on master.
