Matthew Malcomson df6780137d [binutils][aarch64] Bfloat16 enablement [2/X]
Hi,

This patch is part of a series that adds support for Armv8.6-A
(Matrix Multiply and BFloat16 extensions) to binutils.

This patch introduces the following BFloat16 instructions to the
aarch64 backend: bfdot, bfmmla, bfcvt, bfcvtnt, bfmlal[t/b],
bfcvtn2.

Committed on behalf of Mihail Ionescu.

Regression tested on aarch64-elf.

Is it ok for trunk?
