Developing for RISC-V Vector extension (RVV)

--------------------------------------------------------------------------------

Since RVV is not widely available, we still can check validity of implementation

using either QEMU or Spike emulator.

To use Spike one has to specify the toolchain:

```

$ cmake -B rvvbuild -DCMAKE_TOOLCHAIN_FILE=toolchain-rvv-spike.cmake

$ cmake --build rvvbuild

$ cd rvvbuild

```

To use QEMU, please refer to `.github/workflows/rvv-128-clang-17.yml` for

command line options.
