this commit is divided in 4 parts:

Browse Source 
1 - Optimize pixelshadergen to avoid redundant register overflow math, with this if a game don't need this will be not applied.
this must bring some fill rate back and improve speed a little in fill rate limited systems.
2- some corrections to vertexshadergen to avoid uninitialized texture coordinates, dono if is the correct way to fix it but t least it will make house of the dead overkill playable in dx11.
the bad thing: still missing geometri in dx9, in dx11 it works exactly as on opengl.
3 - some optimization made to improve fps a little wih the latests changes made to fifo.
* back to the original code in beginfield as now it will work right.
* check for efb access more often as a lot of time is lost waiting for efb access
4 - apply a little fix for missing textures in nvidia opengl tanks to  Wagnard28 for finding that nvidia does not like invalid shader id :)
please test for any regression
