[testsuite] Add support for -fdump-ada-spec

[Eric Botcazou <ebotcazou at adacore dot com>]

Hi,

the recent breakage of -fdump-ada-spec revealed that the switch isn't 
exercised in the testsuite.  This patch adds the missing support.

Tested on x86_64-suse-linux, OK for mainline?  What of the 4.7 branch?


2012-10-04  Eric Botcazou  <ebotcazou@adacore.com>

	* lib/gcc-dg.exp (cleanup-ada-spec): New procedure.
	* lib/scanasm.exp (get_ada_spec_filename): Likewise.
	(scan-ada-spec): Likewise.
	(scan-ada-spec-not): Likewise.
	* gcc.dg/dump-ada-spec-1.c: New test.
	* g++.dg/other/dump-ada-spec-1.C: Likewise.
