[lto] intN follow-up patch

[DJ Delorie]

This was missed in the big intN patch set I did last year; it only
shows up if you have a target with an N-bit type that isn't also used
for a pointer type but is used for unwinding (which is a change I also
have pending, hence I noticed ;).  Tested on x86-64 and msp430 (with
the pending patch) with no regressions.  Ok?

        * lto-lang.c (lto_type_for_size): Include intN types.
        (lto_type_for_mode): Likewise.
