Implement the FPCR.EBF=1 semantics for bfdotadd() operations:
  * is_ebf() sets up fpst and fpst_odd
  * bfdotadd_ebf() implements the fused paired-multiply-and-add
    operation that we need

The paired-multiply-and-add is similar to f16_dotadd() and
we use the same trick here as in that function, but the inputs
here are bfloat16 rather than float16.
