[v2,00/36] arm: [MVE intrinsics] Re-implement more intrinsics

  Hi,

This is v2 of the patch series I sent in
https://gcc.gnu.org/pipermail/gcc-patches/2024-July/657065.html.

I have taken into account the feedback I received, and added more
patches to the series, converting more MVE intrinsics to the new
framework.

Changes v1-v2:

- I kept patch #1 as-is (so, no change): the comment is a bit verbose,
  but I don't this this causes any harm.
- patch #3: use conditionals in a few more places, making the code
  more compact and hopefully easier to read.
- patch #5: use "su64" instead of "ss8" for the immediate parameter.
- patch #6: restore alphabetical order in arm-mve-builtins-base.def
- patch #7: remove trailing ')' in comments in mve.md
- patch #10: remove trailing ')' in comments in mve.md
- patch #11: remove unused parameter names to avoid warnings.
- patch #13: fix a comment.
- patch #15: fix a comment.

Patches 16-36 are new:
- #16: rework vctp
- #17-21: rework v[id]dup + cleanups
- #22: fix checks of immediate arguments, noticed after the discussion
   on patch #5
- #23-27: rework v[id]wdup + cleanups
- #28-30: rework vshlc
- #31-35: rework vadc/vadci/vsbc/vsbci
- #36: introduce long_type_suffix and half_type_suffix helpers to
   avoid some code duplication.

Tested on arm-eabi with
--target_board=arm-qemu{-mthumb/-mfloat-abi=hard/-march=armv8.1-m.main+mve.fp+fp.dp}
