This change is a bit pedantic, but it makes the ROMs run better in DeSmuMe. Some examples (particularly the dual 3D examples) used to flicker during one or two seconds right after starting. In dual 3D examples the top and bottom screen would start swapped, and they would eventually swap and stop flickering. This would never happen in melonDS or real hardware. I suspect this is because of the interaction between GFX_FLUSH and swiWaitForVBlank(), where there would be some timing difference to reach the first swiWaitForVBlank() or GFX_FLUSH, and that caused the desync. This commit moves swiWaitForVBlank() to the beginning of the game loop. This means that, even in the first iteration of the game loop, all emulators and hardware will be synchronized. This doesn't actually matter in any other situation, it just makes the first iteration consistent.
