Remove check_aligned parameter from vect_supportable_dr_alignment

There are two calls with true as parameter, one is only relevant
for the case of the misalignment being unknown which means the
access is never aligned there, the other is in the peeling hash
insert code used conditional on the unlimited cost model which
adds an artificial count.  But the way it works right now is
that it boosts the count if the specific misalignment when not peeling
is unsupported - in particular when the access is currently aligned
we'll query the backend with a misalign value of zero.  I've
changed it to boost the peeling when unknown alignment is not
supported instead and noted how we could in principle improve this.

	* tree-vectorizer.h (vect_supportable_dr_alignment): Remove
	check_aligned argument.
	* tree-vect-data-refs.c (vect_supportable_dr_alignment):
	Likewise.
	(vect_peeling_hash_insert): Add supportable_if_not_aligned
	argument and do not call vect_supportable_dr_alignment here.
	(vect_peeling_supportable): Adjust.
	(vect_enhance_data_refs_alignment): Compute whether the
	access is supported with different alignment here and
	pass that down to vect_peeling_hash_insert.
	(vect_vfa_access_size): Adjust.
	* tree-vect-stmts.c (vect_get_store_cost): Likewise.
	(vect_get_load_cost): Likewise.
	(get_negative_load_store_type): Likewise.
	(get_group_load_store_type): Likewise.
	(get_load_store_type): Likewise.
