Add a workaround for Intel drivers on glsl function texelfetchoffset GLSL function texelfetchoffset will be translated into texture.Load in ANGLE. In D3D there is a note that When one or more of the coordinates in Location exceeds the u, v, or w mipmap level dimensions of the texture, Load returns zero in all components, but in glsl there is no such restriction, which will cause the WebGL 2 dEQP test deqp/functional/gles3/shadertexturefunction/texelfetchoffset.html fail on Windows with Intel GPU. Adapted from ExpandIntegerPowExpressions.cpp, this patch adds a translation from texelFetchOffset into texelFetch to work around this issue.
