[PATCH 1/1] testsuite: Handle --save-temps in schedule-cleanups

[Christophe Lyon via Gcc-patches]

Some tests use --save-temps, but schedule-cleanups strictly matches
-save-temps, so we leave many temporary files after validation.
Instead of fixing every offending testcase, it's simpler and
future-proof to make schedule-cleanups handle both --save-temps and
-save-temps.
