[33/46] Use stmt_vec_infos instead of vec_info/gimple stmt pairs 

This patch makes vect_record_max_nunits and vect_record_base_alignment
take a stmt_vec_info instead of a vec_info/gimple pair.

2018-07-31  Richard Sandiford  <richard.sandiford@arm.com>

gcc/
	* tree-vect-data-refs.c (vect_record_base_alignment): Replace vec_info
	and gimple stmt arguments with a stmt_vec_info.
	(vect_record_base_alignments): Update calls accordingly.
	* tree-vect-slp.c (vect_record_max_nunits): Replace vec_info
	and gimple stmt arguments with a stmt_vec_info.
	(vect_build_slp_tree_1): Remove vinfo argument and update call
	to vect_record_max_nunits.
	(vect_build_slp_tree_2): Update calls to vect_build_slp_tree_1
	and vect_record_max_nunits.
