Add tests that for-each-ref correctly reports broken loose reference
files and references that point at missing objects. In fact, two of
these tests fail, because (1) NULL_SHA1 is not recognized as an
invalid reference value, and (2) for-each-ref doesn't respect
REF_ISBROKEN. Fixes to come.

Notes (discussion):
Note that a reference that points at NULL_SHA1 is reported as "broken"
rather than "missing". This is because NULL_SHA1 is manifestly bogus,
whereas we have no systematic basis for rejecting any other
40-character hexadecimal string without doing an object lookup.
