This patchset provides an implementation for Zvbb, Zvbc, Zvkned, Zvknh, Zvksh, Zvkg, and Zvksed of the draft RISC-V vector cryptography extensions as per the v20230620 version of the specification(1) (168e7b4).
This is an update to the patchset submitted to qemu-devel on Thu, 22 Jun 2023 05:49:20 -0700,

v2:

    squashed commits into one commit per extension with separate commits for
    each refactoring
    unified trans_rvzvk*.c.inc files into one trans_rvvk.c.inc
    style fixes in insn32.decode and other files
    added macros for EGS values in translation functions.
    updated from v20230303 to v20230407 of the spec:
        Zvkb has been split into Zvbb and Zvbc
        vbrev, vclz, vctz, vcpop and vwsll have been added to Zvbb.

v3:

    New patch 03/19 removes redundant “cpu_vl == 0” checks from trans_rvv.c.inc
    Introduction of new tcg ops has been factored out of patch 11/19 and into 09/19
        These ops are now added to non riscv-specific files

v4:

    New patch 08/17 fixes the tcg_gen_gvec_andcs temporary variable issue
    Patch 09/17 fixes imm mode for vror.vi
    Rebased to riscv-to-apply.next branch (de395bb):
        Replace vstart constraint checking by TCG op
    Verified by code examples provided by vector crypto spec repository (riscv-crypto)

As v20230620 is a frozen version, we are not expecting any significant changes to the specification or this patch series.

Please note that the Zvkt data-independent execution latency extension (and all extensions including it) has not been implemented, and we would recommend not using these patches in an environment where timing attacks are an issue.

Work performed by Dickon, Lawrence, Nazar, Kiran, and William from Codethink sponsored by SiFive, as well as Max Chou and Frank Chang from SiFive.
