[30/46] Use stmt_vec_infos rather than gimple stmts for worklists 

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

gcc/
	* tree-vect-loop.c (vect_analyze_scalar_cycles_1): Change the type
	of the worklist from a vector of gimple stmts to a vector of
	stmt_vec_infos.
	* tree-vect-stmts.c (vect_mark_relevant, process_use)
	(vect_mark_stmts_to_be_vectorized): Likewise
