As bfloat16 is more and more popular in many archs, implement bfloat16
interfaces in softfloat, so that archs can add their bfloat16 insns
based on the blfoat16 interfaces here.

These interfaces have been tested by RISU on RISC-V bfloat16 with
XuanTie C906.

LIU Zhiwei (3):
  fpu/softfloat: Define operations for bfloat16
  fpu/softfloat: Define convert operations for bfloat16
  fpu/softfloat: Define misc operations for bfloat16

Thanks.  Queued to softfloat-next.
