[PATCH v3] aarch64: SVE/NEON Bridging intrinsics

2023-11-09 Thread Richard Ball 
ACLE has added intrinsics to bridge between SVE and Neon.

The NEON_SVE Bridge adds intrinsics that allow conversions between NEON and
SVE vectors.

This patch adds support to GCC for the following 3 intrinsics:
svset_neonq, svget_neonq and svdup_neonq
