fast parser: # type: ignore should ignore non-* imports entirely #1739

        # Skip imports that have been ignored (so that we can ignore a C extension module without
        # stub, for example), except for 'from x import *', because we wouldn't be able to
        # determine which names should be defined unless we process the module. We can still
        # ignore errors such as redefinitions when using the latter form.
