[erlang-patches] Optimize handling of local fun variables in v3_kernel

[Anthony Ramine]

Of course, I sais bug because I was too lazy to be correct.

Do you know of any other unsaid invariants on which behaviour HiPE depends and that might be changed in the future? Wouldn't that be documentation-worthy?

Whenever these invariants get broken, perhaps for very good reasons as in this case, the HiPE compiler also needs to be adapted to not rely on them anymore.  It's a quite natural process in software components that depend on each other that would not classify as a bug.
