Description: Binary data
Thanks for your suggestion!
Indeed, there are still some scenarios that can be optimized and
improved next.

Maybe we should also consider the case $imm = 2^k + 1$ as they can be
implemented with sl[te] and bstrins.[wd]. But it can be done in another
patch anyway.

The new pattern to optimize certain code sequences on RISC-V played
things a bit fast and loose with modes -- some operands were using the
ALLI iterator while the scratch used X and the split codegen used X.

The xvexth related instructions operate SEPARATELY according to
the high and low 128 bits, and sign/zero extend the upper half
of every 128 bits in src to the corresponding 128 bits in dest.
For xvexth.d.w, the rule for the first element of dest should be:
dest.D[0] = sign_extend (src.W[2] ,64
There are two aspects that affect the matching of instruction templates:
