Support for ARM Helium SIMD instructions

[michael-p]

ARM Helium is a SIMD instruction set extension for Cortex-M microcontrollers, currently the Cortex-M55 and Cortex-M85, with 128-bit width. It is already supported by LLVM (intrinsics and auto-vectorization). Will it be possible to use it with the portable SIMD API as well? Thanks!

it already works for most of the operations that don't use architecture-specific intrinsics: https://rust.godbolt.org/z/TxoGKv777

Thanks, I'll close this issue and open more specific issues in case I encounter missing architecture-specific stuff.
