I believe what we want here is something like svext:
def SVEXT : SInst<"svext[_{d}]", "dddi", "csilUcUsUiUlhfd",
MergeNone, "aarch64_sve_ext", [VerifyRuntimeMode], [ImmCheck<2,
ImmCheckExtract, 1>]>;
The current Immediate I don't believe applies here, because in this case we
need to scale the immediate to bytes. Like it was done for svext
