[testcase, arm] Adjust the negative offset of fp memory access in vfp-1.c

[Carrot Wei]

Hi

The patch r169271 conservatively limits the offset of fp memory access to
(-256..1024), but didn't adjust the related test case, so vfp-1.c fails in
thumb2 mode after the patch. This patch modifies test case vfp-1.c accordingly.

Tested with
make check-gcc RUNTESTFLAGS="--target_board=arm-sim/thumb/arch=armv7-a
arm.exp=vfp-1.c"

OK for trunk and 4.6 branch?

thanks
Carrot
