[PATCH][GCC 8] AArch64: Add Neoverse V1 tuning struct

[Kyrylo Tkachov via Gcc-patches]

Hi all,

This GCC 8 patch duplicates the Cortex-A72 tuning struct that's currently used 
for Neoverse V1 and AARCH64_EXTRA_TUNE_PREFER_ADVSIMD_AUTOVEC tune flag to 
prefer Advanced SIMD over SVE autovectorisation.

Bootstrapped and tested on GCC 8, pushing to the branch.

Thanks,
Kyrill
