	* tree-out-of-ssa.c (insert_value_copy_on_edge): If the source
	and destination have different modes, Use promote_mode to
	determine the signedness of the conversion.  Assert that the
	promoted source mode matches the destination mode.  Don't pass
	the destination and destination mode to expand_expr if the source
	mode is different.  Simplify conversion logic.
