Yes, definitely.
I meant to do that for this first cut, but failed to get to it.

That would be great!

Note that we do already have a good place to pass data around the
reader: the lto_context structure. So, it should be a matter of putting
a pointer to the abbreviation information there, and then changing
lto_abbrev_lookup to use the abbreviation table pointed to by
lto_context, rather than assuming there is only one.
If you wouldn't mind, I'd like to review the patch before it goes in.
