Subject: [PATCH] testsuite: scan-lang-dump-times & scan-lang-dump-not

Sigh, last week's success at not breaking things failed with an
incorrect 'fix' this morning.  Let's reduce my confusion by making
lib/scanlang.exp the same on trunk as modules.

	gcc/testsuite/
	* lib/scanlang.exp (scan-lang-dump): Fix breakage.
	(scan-lang-dump-times, scan-lang-dump-not): New.
