tree-vect-slp.c (vect_analyze_slp_instance): Dump constructors we are actually analyzing.

Browse Source 
2019-11-20  Richard Biener  <rguenther@suse.de>

	* tree-vect-slp.c (vect_analyze_slp_instance): Dump
	constructors we are actually analyzing.
	(vect_slp_check_for_constructors): Do not vectorize uniform
	constuctors, do not dump here.

	* gcc.dg/vect/bb-slp-42.c: Adjust.
	* gcc.dg/vect/bb-slp-40.c: Likewise.
