[PATCH, ARM] VFP index range

[Chung-Lin Tang]

Hi Richard,
this is a VFP load/store index range patch that I submitted last
year[1], which you approved at that time, but never got committed.

I've added the Thumb-2 bits I missed then, corrected some stuff in the
testcase, and re-submitting now. Re-tested without regressions. Is this
ok for trunk?

Thanks,
Chung-Lin
