This is a minor cleanup for maybe_register_path to return NULL when

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.

OK?

gcc/ChangeLog:

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

OK
