[AArch64][BFloat] basic AArch64 bfloat support
Summary:
This patch adds the bfloat type to the AArch64 backend:
- adds it as part of the FPR16 register class
- adds bfloat calling conventions
- as f16 is now not the only FPR16 type anymore, we need to constrain a number
of instruction patterns using FPR16Op to help out the TableGen type inferrer
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 are specified in the Arm Architecture
