[Mesa-dev] [PATCH 04/13] i965: Make the constant surface interface take a normal byte size.

This puts the rounding-up logic into the function itself instead of all
the callers having to manage it. Also drop an "unused" comment in gen4,
as the stride *is* used for texbos (and will be for uniforms soon).
NOTE: This is a candidate for the 9.1 branch.
