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

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