recoded some more FPU opcodes, and added 2 new speedhacks: "disable extra VU flags" and "disable extra FPU flags".
...
in the PS2, certain "flags" are set to indicate different statuses. There are flags for overflow, underflow, invalid operation, divide by zero, is Zero, is Negative, etc...
some of these flags are rarely checked by games; so what these speedhacks do is not perform the extra code for flags that are rarely used by games.

okay this took me a while, but i managed to make stuff a bit more organized. -New "Advanced" dialog handles all CPU/VU roundmodes, denormals are zero, and flush to zero options. -Moved GT4 and GoW hacks to the "GameFixes" dialog. -"Disable Underflow Checks" no longer controls DaZ, since the "Advanced" dialog handles that.
...
if you guys don't know what to do in the Advanced dialog, just leave it at the defaults (its called advanced for a reason :p)
Note: if you use Patches to change the roundmode, it will override the roundmode set in the Advanced dialog.

modified the Check Overflow speedhacks. now we have "disable VU Overflow checks" and "disable FPU Overflow checks".
...
they both do the same thing, but one is for the VU recs, and the other is for the FPU recs.
heres how they work:
when Unchecked, pcsx2 performs overflow checks normally.
when Checked, pcsx2 doesn't perform overflow checks, and thus gains a speed boost.
when Greyed, pcsx2 performs additional checks which helps stop SPS (spikey polygon syndrome; i.e. messed up polygons on screen)
Note: FPU recs need some work, they're not setting correct flags. I'll probably implement this by the end of the week. Hopefully it will fix some games that use those flags.

modified the Denormals speed hack; now its "disable underflow checks". -leaving it unchecked makes PCSX2 handle underflow like the real PS2 does. -checking it disables underflow checks and is a bit faster. -making it "grey" sets the DaZ flag, which is what causes the big speedup for intel CPU's.
...
the funny thing is that leaving it checked (black) sometimes fixes games (fixes minor graphic corruption in Initial D: Special Stage)
so try experimenting with it on/off/greyed to see if it fixes graphics for your game.
also, you no longer have to restart PCSX2 for the DaZ hack to work :p

note: SVN r4 is what breaks 64bit Linux builds, not entirely sure what the main problem is.
when reverting some files in the x86 folder, games semi-work on x64 linux, but then crash at one point.
they also crash on x86 windows when reverting those files, so this needs some debugging.
