bfloat16.h was a stub. I've filled it out by porting the c10 implementation, added it to ET_SWITCH and ET_FORALL macros, and hooked it up to promoteTypes. I extended the half_to_float argument to promoteTypes to also coerce bfloat16 to float because I figured anybody who wants to ignore half probably also wants to ignore bf16.
