gsdx: add an auto flush hack to implement a Read Write GS effect. 

It impacts all renderers. It ought to fix issue in GTA radiosity,
Shadows in Jak series. (note shadows will suck in upscaling)

Implementation is really brutal. Expect a massive slow down, but at least we can test the effect
easily.

Normally perf impact will remain reasonable if the game doesn't use a Read-Write effect

Performances number are welcomes (my guess is really awful in HW mode, slow in SW mode).
You can enable it with "UserHacks_AutoFlush = 1"
