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.

Sanity checks now run in a single pass rather than two, and
instead of building a set consisting of all members, it uses
a bit from the transformer flags to remember which members are
not orphaned.
As an additional check, it now checks that members are not
declared more than once.

This makes super calls name-based (no target) and add direct calls with
both receiver and explicit target.
Super call resolution translates the name-based super calls into direct
calls after they have been cloned into the mixin application.
For JS backends, it should suffice to clone mixed-in methods that
contain super calls, but that transformation is not part of this CL.
This also adds a --target option to dartk designating the target to
which the kernel IR should be specialized. The new transformation
is run when --target=vm.
