These are not supported by the fp64 spec though, so they are not really
necessary. There are, however, other cases of opcodes that are not
supported by fp64 and where we have provied a double-precision
implementation anyway. Previous discussion in the mailing list suggested
that we might want to do these if they were easy to provide.

If we finally decide against this, we should probably remove double-precision
handling in sin/cos and pow too.
