OK.  I'll bring over my change from devo.

In theory the whole marking of pointer registers by reg_scan_mark_refs
should be completely reworked to not lose in the presense of global
optimizations.  But I haven't come up with the right conceptual model
yet.

Who knows, that code might even be totally useless now that we
propagate alias information better.
