[COMMITTED 11/31] ada: Simplify management of scopes while inlining

["Marc Poulhiès" <poulhies@adacore.com>]

From: Piotr Trojanek <trojanek@adacore.com>

Code cleanup; semantics is unaffected.

gcc/ada/

	* inline.adb (Add_Scope_To_Clean): Use Append_Unique_Elmt.
	(Analyze_Inlined_Bodies): Refine type of a local counter;
	remove extra whitespace.

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