Changelog:

r1666
Added Vif Error flags to Tags.h.

r1663
microVU: minor change...

r1659
Correct fix for thread affinity in CpuDetect, and fixed commenting in clean_msvc.cmd

r1657
Tags.h: 0x8000000 != 0x80000000.

r1656
Disabled precompiled headers for release builds. This fixes the random crash introduced 2 revisions ago (caused by some crappy IPU code we need to eventually get rid of)
Since the IPU code randomly works/breaks with different changes to pcsx2, eventually we´ll be able to re-enable PCH.
