I think this looks very good.  I like that we're using {push,pop}_cfun
in more places now.  Since nobody has objected, this patch is OK.

(Hopefully, in the future, more of the remainder can be converted to
stack discipline too.  Or, to gcc_assert (cfun == NULL).  For example,
it seems reasonable for the IPA passes to just assert that cfun is NULL
on entry, rather than setting it to NULL; if it's non-NULL on entry,
someone has forgotten to pop it.)

Thanks,
