That's a great idea, but it falls down in practice due to the varying behavior
XMM and x87 opcodes have when being used to simply copy floating point values.
Sometimes the Signalling Nan bit is left alone, sometimes it is converted to a
Quiet Nan.

Going on a quixotic quest to try to compensate for such erratic behavior
results in bloated, slow code, and the marginal benefit is not worth it.
