This is a regression causing lots of cached diagnostics tests not functioning since the cached diagnostics processors are not initialized for those tests which are supposed to test diagnostics caching. The regression is caused by the fix that the typecheck module interface job need to run a typecheck job in the sub-invocation. Now the typecheck module interface job is correctly setup to avoid diagnostics about unsupported file system error.
