With everything classified as Zb[abcs] and pre-0.93 draft-B

remaining support code for RVB.

Note that RVB has been retired for good and misa.B will neither mean

The 1.0.0 version of Zbb does not contain pack/packu/packh. However, a
zext.h instruction is provided (built on pack/packh from pre-0.93
draft-B) is available.

This commit adds zext.h and removes the pack* instructions.

Note that the encodings for zext.h are different between RV32 and
RV64, which is handled through REQUIRE_32BIT.

a1095bdcb0 target/riscv: Add rev8 instruction, removing grev/grevi
The 1.0.0 version of Zbb does not contain grev/grevi.  Instead, a
rev8 instruction (equivalent to the rev8 pseudo-instruction built on
grevi from pre-0.93 draft-B) is available.

This commit adds the new rev8 instruction and removes grev/grevi.

Note that there is no W-form of this instruction (both a
sign-extending and zero-extending 32-bit version can easily be
synthesized by following rev8 with either a srai or srli instruction
on RV64) and that the opcode encodings for rev8 in RV32 and RV64 are
different.

daf866b606 target/riscv: Consolidate RV32/64 32-bit instructions
This patch removes the insn32-64.decode decode file and consolidates the
instructions into the general RISC-V insn32.decode decode tree.

This means that all of the instructions are avaliable in both the 32-bit
and 64-bit builds. This also means that we run a check to ensure we are
running a 64-bit softmmu before we execute the 64-bit only instructions.
This allows us to include the 32-bit instructions in the 64-bit build,
while also ensuring that 32-bit only software can not execute the
instructions.
