a3fc129bfd Re-enabled the division by zero check code because it was necessary for Parasite Eve PSF (or maybe it shouldn't be?) and tweaked it a little bit to make it work with the new JIT using 64-bits registers.

8653d52a37 Removed division by zero check in MIPSIV DIV template, because the code it was generating was too big for the x64 compiler (we might want to fix that later though).
