sem_function::bb_dict_test should take a vec<int> *

bb_dict_test () ment to operate on the callers vector, not a copy of it.

gcc/ChangeLog:

2015-02-18  Trevor Saunders  <tsaunders@mozilla.com>

	* ipa-icf.c (sem_function::equals_private): Adjust.
	(sem_function::bb_dict_test): Take a vec<int> * instead of
	auto_vec<int>.
	* ipa-icf.h (bb_dict_test): Likewise.
