50f9f9eba1 Move S9xSyncSpeed call. 
DMA can last multiple frames, and so can S9xMainLoop.
If we throttle outside of S9xMainLoop or only as we're exiting the
loop as is currently done, we zoom through multiple frames and
overrun the audio. Moving S9xSyncSpeed just after EndScreenRefresh
causes it to be called every frame.

This seemingly wasn't a problem because throttling with vsync *did*
happen every frame regardless. Oops.

daf8fba09c Remove extra variables for interlace field. 
Keeping unsynchronized copies around is just asking for trouble.
Instead, use a macro to check the actual memory address.

It's deprecated, and any compiler we use now ignores it.
