Log message:
	* tree-vect-analyze.c (vect_mark_relevant): Third argument "bool
	relevant_p" changed to "enum vect_relevant relevant".  Record the
	max of STMT_VINFO_RELEVANT and 'relevant' instead of their or.
	(vect_stmt_relevant_p): Third argument "bool relevant_p" changed to
	"enum vect_relevant relevant".  Record the value "vect_used_in_loop"
	instead of "true".
	(vect_mark_stmts_to_be_vectorized): Variable "bool relevant_p" changed
	to "enum vect_relevant relevant".  For reduction case, set relevant to
	"vect_used_by_reduction" instead of "true".
	* tree-vect-transofrm.c (vectorizable_type_promotion): Pass 'stmt' to
	supportable_widening_operation, instead of 'orig_stmt_in_pattern'.
	* tree-vectorizer.c (new_stmt_vec_info): STMT_VINFO_RELEVANT_P replaced
	with STMT_VINFO_RELEVANT. Initialize STMT_VINFO_LIVE_P to false instead
	of 0.
	(supportable_widening_operation): Check STMT_VINFO_RELEVANT instead of
	checking immediate uses.
	* tree-vectorizer.h (vect_relevant): New enum type.
	(_stmt_vec_info): Field relevant changed from bool to enum vect_relevant.
	(STMT_VINFO_RELEVANT): New macro to access the field 'relevant'.
	(STMT_VINFO_RELEVANT_P): Changed to check the value of field 'relevant'.
