aarch64: ACLE intrinsics for BFCVTN, BFCVTN2 and BFCVT
This patch adds the Armv8.6-a ACLE intrinsics for bfcvtn, bfcvtn2 and
bfcvt as part of the BFloat16 extension.
(https://developer.arm.com/architectures/instruction-sets/simd-isas/neon/intrinsics)
The intrinsics are declared in arm_bf16.h and arm_neon.h and the RTL
patterns are defined in aarch64-simd.md.
