re PR middle-end/50650 (ICE in vect_is_simple_use_1, at tree-vect-stmts.c:5689) 

PR tree-optimization/50650
	* tree-vect-patterns.c (vect_recog_mixed_size_cond_pattern): Don't
	call vect_is_simple_cond here, instead fail if cond_expr isn't
	COMPARISON_CLASS_P or if get_vectype_for_scalar_type returns NULL
	for cond_expr's first operand.
	* tree-vect-stmts.c (vect_is_simple_cond): Static again.
	* tree-vectorizer.h (vect_is_simple_cond): Remove prototype.

	* gcc.c-torture/compile/pr50650.c: New test.
