FWIW, I'm fine with the changes to the jit subdir, but I don't think I
have approval rights on the vec.h changes.

BTW, was the move of vec_alloc in vec.h intentional?  (I take it that
it's the same before/after, but it seems to have added some churn to
the vec.h part of the patch).

Hi.

Good, I'll wait a review from a global reviewer.

It's not intentional, fixed in attached patch.
