256b wide SVE vectors allow some simplification of truffle. Up to 40% speedup on graviton3. Going from 12500 MB/s to 17000 MB/s onhe microbenchmark. SVE2 also offer this capability for 128b vector with a speedup around 25% compared to normal SVE Add unit tests and benchmark for this wide variant Signed-off-by: Yoan Picchi <yoan.picchi@arm.com>
