re PR tree-optimization/69083 (ICE at -O3 in 64-bit mode on x86_64-linux-gnu (verify_gimple failed))

	PR tree-optimization/69083
	* tree-vect-slp.c (vect_get_constant_vectors): For
	VECTOR_BOOLEAN_TYPE_P assert op is fold_convertible_p to vector_type's
	element type.  If op is fold_convertible_p to vector_type's element
	type, use NOP_EXPR instead of VCE.

	* gcc.dg/vect/pr69083.c: New test.
