Interpreter: software-based flush-to-zero

Browse source 
bDAZ is now called bFlushToZero to better reflect what it's actually
used for.

I decided not to support any hardware-based flush-to-zero on systems
that don't support this for both inputs _and_ outputs. It makes the code
cleaner and the intersection of CPUs that support SSE2 but not DAZ
should be very small.
