fix vectorizer memleaks

Browse Source 
This plugs two memleaks in the vectorizer.

2021-01-08  Richard Biener  <rguenther@suse.de>

	* tree-vect-slp.c (scalar_stmts_to_slp_tree_map_t): Fix.
	(vect_build_slp_tree): On cache hit release the matched
	scalar stmts vector.
	* tree-vect-stmts.c (vectorizable_store): Properly free
	vec_oprnds before possibly gathering them again.
