[COMMITTED 19/35] ada: Fix internal error on function call in class-wide precondition

[Marc Poulhiès]

From: Eric Botcazou <ebotcazou@adacore.com>

This occurs when the call is to a function that is declared in a package
that is nested in the scope where the type declaration is located.

gcc/ada/ChangeLog:

	* freeze.adb (Freeze_Expression.In_Expanded_Body): Also return True
	for the body of a helper/wrapper built for class-wide preconditions.

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