[PATCH 1/4] sched-deps: clear dependency caches before freeing them

From: Kyrylo Tkachov <[email protected]>

sched_deps_finish resets cache_size before it uses cache_size to clear the
dependency cache bitmaps.  The cleanup loop therefore has zero iterations.
The cache arrays are freed, but their bitmap elements are not returned to
the bitmap obstack.

Move the reset after the cleanup loop.

Bootstrapped and tested on aarch64-none-linux-gnu and x86_64-linux.

gcc/ChangeLog:

	* sched-deps.cc (sched_deps_finish): Reset cache_size after clearing
	and freeing the dependency caches.
