Generalized a pile of duplicated type caching code, but it's still
largely undeployed because I haven't figured out how to make it as fast
as the copy-pasted version, which bugs me like you wouldn't believe.
Cannot deal with making "Sophie's Choice" between performance and lack
of duplication. I left one deployment in because it fixed a bug, or at
least so I see it: can't see why one would want the two absent error
messages in t2641.check. Review by odersky.
