* misc-speedups:
fixed and reenabled and slightly optimized the JIT version of fcmpo/fcmpu.
slightly more precise speed percent display (this is really minor)
a small thread synchronization speedup for dual core mode. it's most noticeable in games where the CPU is running behind compared to the GPU.

The Fifo.cpp changes from rdaefb3b550e2 was not merged as there was no performance benefit.
This branch reduces the number of useless state flushes in the video
emulation layer by checking whether a BP/XF change will have an effect
or not. Greatly reduces the number of GL calls per frame.
Thanks to degasus for his help!
When a game writes the same value that was already configured to a BP
register, Dolphin previously flushed the GPU pipeline and reconfigured
the internal video state (calling SetScissor/SetLineWidth/SetDepthMode).
Some of these useless writes still need to perform actions, for example
writes to the EFB copy trigger or the texture preload registers (which
need to reload the texture from memory).
This allows users to easily check whether their Wii dump is corrupted or not
using the Dolphin properties window. Right click on a game, Properties,
Filesystem tab, then right click on the game partition and select "Check
partition integrity".
This may have some false negatives due to the unused clusters heuristic (see
the comment in VolumeWiiCrypted.cpp). False positives are unlikely.
* JIT-Exceptions:
JitIL code cleanup
Changed the JIT code to make the FPU exception timing more accurate. The exception is now triggered at the first FP instruction instead of the start of the block. Rearranged the JIT exception code for a tiny speed-up. Only external exceptions are checked at the end of the block. All other exceptions are checked at the time they occur.
Fixes issue 5382.
