In detail this patch

- march options for armv8.6-a
- BFloat16 assembly

This is part of a patch series, starting with command-line and Bfloat16                                                                                                                                       
assembly support. The subsequent patches will upstream intrinsics                                                                                                                                             
support for BFloat16, followed by Matrix Multiplication and the                                                                                                                                               
remaining Virtualization features of the armv8.6-a architecture.
