For example if width were 65, the first slice would get 96 while the
second would get 32. However the hardware appears to expect the second
pitch to be 64, based on halving the 96 (and aligning up to 32).
This fixes texelFetch piglit tests on a3xx.

Still need to run this through piglit, but the initial texelFetch
results are encouraging. There still seems to be some horrible problem
with array textures e.g. sampler2DArray 100x100x5, but it actually
feels related to rendering rather than sampling.
