Fix ogl screenshots for windows.
Fix the macosx build (perhaps).
This changes the JitIL timed profiling to using assembly language to obtain the time. It does seem to be faster. Not sure if it will work on macosx, but if it does it has the necessary precision that gettimeofday does not have.
Implement JitIL profiling on linux. I also tried implementing __rdtsc using assembly and didn’t really see a speed improvement so went with clock_gettime.
Also changed other gettimeofday calls to clock_gettime, which is supposedly more accurate.
