Add coverage for the v8.2 DP and v8.2 FHM insns in the Neon extension
space.  (We already had the v8.1 VQRDMLAH/VQRDLSH and the v8.3
VCADD/VCMLA, so this brings the risu coverage into line with what
QEMU has implemented so far.)

I added these patterns as part of testing for the first part
of the Neon decodetree conversion and forgot I'd never sent out the
risu patch for review.

Sorry I didn't submit these myself February last year.  I still have them
sitting in a separate .risu file that I used for testing originally.
