"make check" fails on alpha in tFile. It seems gp in itoa () in
libio/stream.cc has some garbage.

Does this look like a right fix?

Thanks.

        * alpha.md (call patterns): Revert Oct 16 change; if we are to elide
        the callee's ldgp, we must do it ourselves, and we use the jsr tag
        for more than scheduling.
