It's fine that it will generate code that cannot be linked, as long as we don't
have runtime use. We just need to check generated IR.

This patch looses the cast check (`canLosslesslyBitCastTo`) and leaves it to the
one inside `CreateBitCast`. It seems too conservative for the use case here.

The patch is in a good shape now. I have made two other prime patches (#81674
and #81669). I'll rebase this one once they are landed.
This patch only changes one bf16 instruction with the necessary infrastructure
for others. I'll update all of them once this patch is landed.
