Previously, the code used a lot of "bitwise AND" to get specific bitfields of the interrupt mask control register, which makes the code look a bit hacky, also it's even more hard for normal people to calculate the value when hexadecimal values are used for the bitwise operations where the register is totally binary. Instead of dealing with all those mess, let's just get the bitfield values from the already implemented nice union of the IMR register. FWIW it also makes the code more readable.
Aligning GIF packets on state save actions seems to cause some issues with the hack.
Still hope to find a better solution.

Threading VU1 took a lot of rewrites and new code to make possible (MTGS, microVU, gifUnit...), but we finally got to the point where it was feasible, and now we've done it! (so now everyone can stop complaining that pcsx2 only takes advantages of 2 cores :p).
The speedups in the games that benefit from it are great if you have a cpu with 3+ cores (generally a 10~45% speedup), however games that are GS limited can be a slowdown (especially on dual core cpu's).
The option can be found in the speedhacks section as "MTVU (Multi-Threaded microVU1)". And when enabled it should should show the VU thread-time percentage on the title bar window (Like we currently do for EE/GS/UI threads).
It is listed as a speedhack because in order for threading VU1 to have been a speedup, we need to assume that games will not send gif packets containing Signal/Finish/Label commands from path 1 (vu1's xgkick). The good news is very-few games ever do this, so the compatibility of MTVU is very high (a game that does do this will likely hang).
Note: vs2010 builds and Linux builds need to be updated to include "MTVU.h" and "MTVU.cpp".

- Fixed a bug with mVU's ESIN implementation. This finally fixes the flower-petal bug in Radiata Stories (and hopefully the clouds-bug in VP2 but havn't tested). Rama and I have wanted to fix this for a long time, but never knew the problem :p
- Improved implementation of some undefined behavior that happens on branches to take into account pipeline stalls.
gif / vif:
- Added some logging code that parses gif packets. It can be enabled by the PRINT_GIF_PACKET macro in Gif.h
- Deleted some old gif code.
- On ReadFIFO_VIF1() clear the out-reg to prevent uninitialized results in case GSreadFIFO() doesn't modify it...
- Create a fallback for GSreadFIFO2() so that its always defined (as long as the plugin implements GSreadFIFO())
pcsx2:
- Organized the virtual folders in vs2008 a bit...
Note: vs2010 and Linux builds need to be modified to add Gif_Logger.cpp and delete GIFpath.cpp

fixes Bleach bankai problem, and probably other games (wizardry/growlancer 3) but haven't tested...
Also removed a vif FlushA hack that used to be needed for tekken 4/gitaroo man but not anymore...

Pcsx2 now has a gifUnit class which acts like the ps2's gif and executes a single gif transfer at a time (and performs path arbitration according to priority and path3 slicing).
This new code is generally a speedup for most games. Particularly VU heavy games like GoW.
This revision breaks old saved state compatibility so don't update if you wish to keep playing with your old saved states.
Leave comments if this revision fixes or breaks anything...
Message to GS Plugin authors:
This new code now uses only 1 gif callback to transfer data to the gs plugin (GSgifTransfer).
pcsx2 also is garaunteed to send full GS primitives to the plugin. So you don't have to account for partial-transfers anymore.
Thanks goes out to shadowlady who tested around 500 games for me :D
Note 1: The old gif code is still in this revision, and can be enabled by the USE_OLD_GIF macro. The old code will be deleted soon.
Note 2: This revision also enables assertion dialogs in devel builds, and changed a lot of assume cases into assertions.
