- introduced isInstanceOf$erased and asInstance...
- introduced isInstanceOf$erased and asInstanceOf$erased methods, which
work on the erased types; things to note:
* before TypesAsValues phase, either variant can be used, although
the erased ones need to be used with caution, when speed
matters;
* after TypesAsValues phase, only the erased variants should be
used (done automatically by TreeGen);
* when run time types are disabled, the TypesAsValues phase is not
skipped anymore: it is turned into a trivial phase which
rewrites all non-erased instanceof/casts into erased ones.
