[incremental] Patch: FYI: add missing smashed type check

I'm checking this in on the incremental-compiler branch.

This adds a missing smashed type lookup that I found while building

The incremental compiler can now build gdb (I only tried the gdb/
subdir, not the whole tree).  It isn't hugely faster (6%), but of
course for C I expect the gains to come from incremental code
generation -- the next phase.
