LukeGeeson added a parent revision: D81486: [ARM][BFloat] Implement lowering of bf16 load/store intrinsics.

This patch upstreams support for BFloat Matrix Multiplication Intrinsics
and Code Generation from __bf16 to AArch32. This includes IR intrinsics. Unittests are
provided as needed.

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

The bfloat type, and its properties are specified in the Arm
Architecture
