This is not complete, but shows the direction I'd like to go.

Version 2 extracts more bits from my sve2 branch.  There's
still more to pull back, especially for crypto_helper.c, where
there are also tail clearing bugs to fix.

Version 3 rebases on master, which has some of the arm neon
decodetree conversion applied.

Something in this patchset produces a failure on VRSRA:
testcases/aarch32-all-v80/insn_VRSRA__INC.risu.bin
from Alex's set produces different results.
