Making the fastest Dolphin version ever

[dephined]

Every time I downloaded/tried a new Dolphin dev build, I compared it to the previous, so I know perfectly what I'm saying: on my system those PRs slowed the code.
Of course in the meantime others PRs optimized Dolphin, but without the ones that I mentioned it could be much faster.

P.S. ask Skidau if the hotkey PR didn't slowdown Dolphin...he had to make another PR to fix the "callings" of the code (because they were too much), but even with the fix the performance stayed slightly below as it was before...
