For the record, the only change on x86, where x87 FPU code is used
anyway, is a flds instruction (load of float) changed to a fldl (load
of double), which is pretty harmless speedwise.

And if the code really matters, simd is pretty simple on such code.

There are a number of places where some code defines its own value,
and I'm not sure float vs double is checked either.
