[PATCH, ARM] Fix broken testcase, vfp-1.c, for Thumb

[Ian Bolton]

This patch makes the vfp-1.c testcase work for Thumb.  It became broken when
we
restricted the negative offsets allowed for Thumb to fix up a Spec2K failure
some months back.  (It was previously possible to generate illegal offsets.)

OK for trunk?


Cheers,
Ian
