I'm not sure if we support architectures without a "tf" floating point type. To be safe I believe we still need a guard here since this file is compiled unconditionally. We just have to replace it with "CRT_HAS_F128".

A nice future cleanup would be to change CRT_HAS_TF_MODE to actually mean tf_float exists and explicitly guard for INT128 where needed. But that is a larger cleanup that probably shouldn't be part of this PR.
