Reduce the number of aligned_access_p calls

Browse Source 
This uses the computed alignment scheme in vectorizable_store
much like vectorizable_load does instead of re-querying
it via aligned_access_p.

2021-10-18  Richard Biener  <rguenther@suse.de>

	* tree-vect-stmts.c (vectorizable_store): Use the
	computed alignment scheme instead of querying
	aligned_access_p.
