I think the issue shows up when running the tests against a workspace
(e.g. when the tests get run from tools/bootcheck).
The workspace typically gets compiled with a C grade,
but the IL tests need a .opt file that was built with an IL grade.

One solution would be to just disable the IL tests when running the tests in
a workspace.  But that is undesirable since it means that people might
accidentally break the IL grade and we wouldn't find out until after their
changes are checked in.

Is there any particular problem with Pete's change?
If not, I'd rather include it, even though it's not strictly necessary,
since it means we can have better test coverage when running tests
against a workspace.
