Hi all,
Please disregard patch v2, some necessary changes have become apparent after
submission.
I will make these changes and submit as patch v3.
Apologies,
Richard Ball

Subject: [PATCH v2] aarch64: SVE/NEON Bridging intrinsics
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
