Return NULL for maybe_register_path when unprofitable.
This is a minor cleanup for maybe_register_path to return NULL when
the path is unprofitable. It is needed for a follow-up patch to
generate better dumps from the threader.
There is no change in behavior, since the only call to this function
bails on !profitable_path_p.
Tested on x86-64 Linux.

* tree-ssa-threadbackward.c (back_threader::maybe_register_path):
Return NULL when unprofitable.
