From: Piotr Trojanek <troja...@adacore.com>
Code cleanup following a fix for aspect Exclusive_Functions; semantics
is unaffected.
gcc/ada/
* exp_ch9.adb (Build_Protected_Subprogram_Body,
Build_Protected_Subprogram_Call_Cleanup): Reuse refactored
routine.
* sem_util.adb
(Has_Enabled_Aspect): Refactored repeated code.
(Is_Static_Function): Reuse refactored routine.
* sem_util.ads (Has_Enabled_Aspect):
New query routine refactored from repeated code.
Tested on x86_64-pc-linux-gnu, committed on master.
