When inlining rules, don't walk the dragonfly graph again; instead stitch Gs

kaldi.compiler (Level 15): KaldiRule(51, mygrammar::phony_my_cursorfree_bottom_simple): Compiling 2206state/6525arc FST to 4831e0d55373b59ae91bf8466cb438ee.fst
Seems like the rules depending on other, complex, rules generate a lot of states and arcs.

yeah, the kaldi engine actually inlines rules
patched
Curious; Is that possible to disable?
daanzu (David Zurow)
currently no. i can't remember the details very clearly, but i remember thinking there was a way to maybe avoid that but it would be a bit of work
i don't think that should be causing much of a problem for memory or compilation speed
hmm, well it does have to walk the dragonfly grammar more times
so compilation speed yes
i could stitch the Gs together to save some time.
