ada: Add escape hatch to configurable run-time
Before this patch, the fact that Restrictions pragmas had to fit on
a single line in system.ads was difficult to reconcile with the
80-character line limit that is enforced in that file.
The special rules for pragmas in system.ads made it impossible to us
the Style_Checks pragma to allow long Restrictions pragmas. This patch
relaxes those rules so the Style_Checks pragma can be used in
system.ads.
gcc/ada/
* targparm.adb: Allow pragma Style_Checks in some forms.
* targparm.ads: Document new pragma permission.
