claim this is C.  We don't make ElaboratedTypes in C, but sometimes
the language options during pretty-print lie to us.

The rewriter should really be fixed to not rely on how types are pretty-printed,
though.

Really apply (unnoticed weird git-svn merge conflict in 98144): Refactor RegionStore::RemoveDeadBindings to use the same core cluster analysis algorithm as RegionStore::InvalidateRegions().

Beyond simplifying the algorithm significantly, we no longer
need to build subregion maps in RemoveDeadBindings().  This
and other changes cause a significant speedup: the time to
analyze sqlite3.c (single core) drops by 14%.
