[PATCH] aarch64: Update flags for bfloat16 builtins

[Kyrylo Tkachov via Gcc-patches]

Hi all,

This patch updates the flags for the bfloat16 builtins.
The bfdot ones aren't affected by the FPCR/FPSR so can be AUTO_FP
whereas the bfmlal ones follow the normal floating-point instructions and get 
FP.

Bootstrapped and tested on aarch64-none-linux-gnu.
Pushing to trunk.
Thanks,
Kyrill

gcc/ChangeLog:

        * config/aarch64/aarch64-simd-builtins.def (bfdot_lane, bfdot_laneq): 
Use
        AUTO_FP flags.
        (bfmlalb_lane, bfmlalt_lane, bfmlalb_lane_q, bfmlalt_lane_q): Use FP 
flags.
