This patch adds BFloat MVT support. It also adds fixed and scalable vector MVT
types for BFloat.

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

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