[Mesa-dev] [PATCH 54/56] i965: pad out brw_stage_prog_data pointers to 64bits

[Timothy Arceri]

In order for this struct to have the same size on 64bit and 32bit
platforms we uses unions to make sure the pointers always take up
at least 64bits. This is useful for making sure we always write
the same size data to disk in the shader cache.
