[COMMITTED] ada: Add missing SCO generation for quantified expressions in object decl

[Marc Poulhiès]

From: Léo Creuse <creuse@adacore.com>

This change corrects the Has_Decision predicate in par_sco.adb to
properly consider predicates of quantified expressions as
decisions.

gcc/ada/

	* par_sco.adb (Has_Decision): Consider that quantified expressions
	contain decisions.

Tested on x86_64-pc-linux-gnu, committed on master.
