Jordan Rose eb4ade4462 Honor @testable import for internal decls in ValueDecl::isAccessibleFrom. ...

We can now use internal declarations safely and correctly in source files!
The remaining work is to make sure testable imports work reliably through
modules, which is important for debugging unit tests.

It's also possible this work will affect compile time, but for the most
part we don't have large quantities of internal declarations that are
being ignored, and some day we will strip them out of non-testable modules
altogether.
