VEC_COND_EXPR verification adjustment

This adjusts GIMPLE verification with respect to the VEC_COND_EXPR
changes forcing a split out condition.

2021-04-14  Richard Biener  <rguenther@suse.de>

	* tree-cfg.c (verify_gimple_assign_ternary): Verify that
	VEC_COND_EXPRs have a gimple_val condition.
	* tree-ssa-propagate.c (valid_gimple_rhs_p): VEC_COND_EXPR
	can no longer have a GENERIC condition.
