Asger Feldthaus 8f12489839 Add --verify-ir flag to dartk and test.py.
This replaces the old --sanity-check flag from dartk. Some files have
been renamed to avoid the wording "sanity check".

Compared to --sanity-check, the following checks have been added:
- variables are not referenced out of scope
- variables are not redeclared
- class type parameters are not referenced from static context

A unit test has been added to check that the verifier rejects certain
invalid ASTs.
