[PATCH] Add newline when checking path profitability.

[Aldy Hernandez <aldyh@redhat.com>]

It looks like we're missing a newline for cases where we don't print
anything.

OK?

gcc/ChangeLog:

	* tree-ssa-threadbackward.cc (possibly_profitable_path_p): Always
	add newline.
	(profitable_path_p): Same.
