Merge branch 'immediate-removal' into GLSL-master
Conflicts: Source/Core/VideoCommon/Src/PixelShaderGen.cpp Source/Plugins/Plugin_VideoSoftware/Src/SWRenderer.cpp immediate-removal is a new created branch seperated from master but reverted the revert of immediate-removal so we get less conflicts by merging
