llvmpipe: enable ARB_texture_gather
Just announce support for 4 components.
While here also increase the max/min texel offsets (the limit is completely
artificial, was chosen because that's what other hardware did, however there's
other drivers using larger limits).
Over a thousand little piglits skip->pass.
v2: update docs/GL3.txt
