* Moved handling of emulated floating point negation into new virtual method tcgunaryminusnode.second_float_emulated. Also changed it into simple flipping of the sign bit, which is how it is defined by IEEE 754, and already done for ARM targets. Relevant ARM-specific parts can now be removed, and m68k code gets significantly better without further efforts.
