Pass more vector types to append_pattern_def_seq

The PR85694 series added a vectype argument to append_pattern_def_seq.
This patch makes more callers use it.

2018-07-03  Richard Sandiford  <richard.sandiford@arm.com>

gcc/
	* tree-vect-patterns.c (vect_recog_rotate_pattern)
	(vect_recog_vector_vector_shift_pattern, vect_recog_divmod_pattern)
	(vect_recog_mixed_size_cond_pattern, adjust_bool_pattern_cast)
	(adjust_bool_pattern, vect_recog_bool_pattern): Pass the vector
	type to append_pattern_def_seq instead of creating a stmt_vec_info
	directly.
	(build_mask_conversion): Likewise.  Remove vinfo argument.
	(vect_add_conversion_to_patterm): Likewise, renaming to...
	(vect_add_conversion_to_pattern): ...this.
	(vect_recog_mask_conversion_pattern): Update call to
	build_mask_conversion.  Pass the vector type to
	append_pattern_def_seq here too.
	(vect_recog_gather_scatter_pattern): Update call to
	vect_add_conversion_to_pattern.
