(MIPS R5900) Adding support for the FPU (COP1) instructions

[Woon yung Liu]

Hi all,

I realized that implementing support for the FPU probably isn't a very good idea, even if it can be done. As there is no way to preserve the contents of $ACC, it would be possible for other threads and interrupt handlers to overwrite the content of $ACC in-between a chain of MADDs or MSUBs.

Anyway, thanks for your patience and help.

Thanks and regards,
