FWIW, vendor-sys/illumos is merged to sys/cddl/opensolaris, but in
FreeBSD, dis_tables.c lives at sys/cddl/dev/dtrace/x86/dis_tables.c
for some reason. That is, it's not under the merge target, so merging
from vendor-sys/illumos might not be possible without first moving
dis_tables.{c,h} to sys/cddl/opensolaris/common/dis.

I think that's at least part of the reason dis_tables.c has been
updated directly in the past, so I don't think it would be problematic
to keep doing it that way until dis_tables.{c,h} are moved (assuming
that that's sufficient to start merging them from vendor-sys). I'm not
100% sure of this though.
