tree-vect-patterns.c (widened_name_p): Rename to ... 

ChangeLog:

	* tree-vect-patterns.c (widened_name_p): Rename to ...
	(type_conversion_p): ... this.  Add new argument to determine
	if it's a promotion or demotion operation.  Check for
	CONVERT_EXPR_CODE_P instead of NOP_EXPR.
	(vect_recog_dot_prod_pattern): Call type_conversion_p instead
	widened_name_p.
	(vect_recog_widen_mult_pattern, vect_recog_widen_sum_pattern,
	vect_operation_fits_smaller_type, vect_recog_widen_shift_pattern):
	Likewise.
	(vect_recog_mixed_size_cond_pattern): Likewise and allow
	non-constant then and else clauses.

testsuite/ChangeLog:

	* gcc.dg/vect/slp-cond-3.c: New test.
	* gcc.dg/vect/slp-cond-4.c: New test.
