Basic errors:
- Inlining of generic functions is not yet supported.

We can't express tests for the error resulting from inlining a
conversion T(x), a call to a literal func(){}(), a call to a
func-typed var, or a call to an interface method, since all of these
cause the test driver to fail to locate the callee, so
it doesn't even reach the Indent function.
