Fixes some small bugs that blocked the specs from running. So rake spec
should now report 1325 specs running with 0 failures. The spec baseline
needs to be reset given the large amount of work that Tomas has put into
the compiler. Will do this in a separate check-in.
We also need to update the specs to the latest version in rubinius. That
will be done this week so that we can continue to push on the compiler
to see if we can run their new spec runner without any modifications.
