This patch adds the bfloat16_t struct typedefs (e.g. bfloat16x8x2_t) to
arm_neon.h

This patch is part of a series implementing the Bfloat16 extension of the
Armv8.6-a architecture, as detailed here:

https://community.arm.com/developer/ip-products/processors/b/processors-ip-blog/posts/arm-architecture-developments-armv8-6-a

The bfloat type, and its properties is specified in the Arm C language
extension specification:
