FPU fixes:
tweaked the fpu compare clamping so now gt4 works again. made the digimon rumble arena 2 fix into a gamefix. tekken 5 doesn't need a gamefix anymore. VU fixes: fixed 2 opcodes thanks to nneeve. optimized FCOR a bit. changed the way ICO gamefix works so its less hacky (just always sets VI to 1 instead of setting VI to the opposite of the 'correct' result) General fix: there was some odd bug with the autogenerated TEXTINCLUDE stuff. if you edited a resource, it would generate #include "afxresmw.h instead of #include "afxresmw.h" (a quotation mark was missing so you'd get compile errors) so i fixed that ;p git-svn-id: http://pcsx2.googlecode.com/svn/trunk@563 96395faa-99c1-11dd-bbfe-3dabce05a288
