A repeated null value at the end of an input record with a count > 1
would incorrectly advance to the next record when resumed. Fix.
Improve some poor naming and code flow noticed while debugging, so
next time will be easier.
Extend a unit test to check this case.

Port external-io test to use GTest. Remove Runtime tests directory.
Rename RuntimeGTest directory to Runtime.
This is the last in a series of patches which ported tests from the old
flang/unittests/Runtime test directory to use GTest in a temporary
unittest directory under flang/unittests/RuntimeGTest. Now that all the
tests in the old directory have been ported to use GTest, the old
directory has been removed and the GTest directory has been renamed to
flang/unittests/Runtime.
