sampler_array_indexing: Check that the texture coordinates work
Previously the various sampler_array_indexing shaders were using a
checkerboard texture with identical colours for each part of the grid.
That meant that it didn't actually matter what texture coordinates
were used to sample. This patch changes it so that they all have a
dark red colour for one of the colours and then it ensures that the
texture coordinates should sample from a space with the other colour.
The main reason to do this is that in Mesa with the i965 driver the
texture coordinates aren't actually getting passed correctly with the
vec4 backend (ie, for vs and gs). That means these tests now fail and
correctly identify the problem.
