JIT: remove unnecessary pxor in paired stores

I don't think this is necessary anymore?
Fix wiimote speaker divisor.

Playing with the wiimote volume in the Wii menu in-game, I found that the range for m_reg_speaker.volume is 0 -127, not 0 - 64.
Remove runtime OS X version check.

My recent update to that check broke compilation on 10.9:
https://code.google.com/p/dolphin-emu/issues/detail?id=7900

However, on further review, the check isn't actually necessary.  If the
OS X version is older than LSMinimumSystemVersion in Info.plist, the
system will generally refuse to run the binary in the first place.  You
can try to launch it via a terminal, but at that point it's the user's
problem if it crashes.
