fd637030e4 GeometryShaderGen: Consistently use xfmem just as the vertex shader. 
There are very rare conditions in which xfmem can actually desync from bpmem.

1b771deb56 Move worldpos into it's own varying. 
Previously it was packed into spare slots in clippos.xy and normal.w,
but it's ugly and more importantly it's causing bugs.

This was discovered during the debugging of a zfreeze branch, which
expected clippos.xy to be xy position coordinates in clipspace (as
the name suggested).

Turns out the stereoscopy shader had also run into this trap, modifying
clippos.x (introducing errors with per-pixel lighting).

This commit has been moved outside of the zfreeze PR for fast merging.

0d79e8f32b VideoCommon: Don't specify the redundant in/out qualifier if GL_ARB_shading_language_420pack is supported. 
Some driver developers interpreted "can" as "must" in the OpenGL specs. (I'm looking at you AMD)

27f3f804a0 ShaderGen: Only pass VS_OUTPUT between shaders if stereo 3D is enabled. 
GLSL130 doesn't support passing structs between shaders.
This is not a problem for stereo 3D which has a GLSL150 requirement.
