blorp: Use normalized coordinates on Gen6
Apparently, the sampler has some sort of precision issues for
non-normalized texture coordinates with linear filtering. This caused
some small precision issues in scaled blits. Work around this by using
normalized coordinates. There is some extra work necessary because Gen6
uses TEX (instead of TXF) for some multisample resolve blits.
Fixes piglit.spec.arb_framebuffer_object.fbo-blit-stretch on SNB.
