anv: Round u_vector element sizes to a power of two
This fixes 32-bit builds of the driver. Commit 08413a81b93dc537fb0c3 changed things so that we now put struct anv_states in the u_vector for binding tables. On 64-bit builds, sizeof(struct anv_state) is a power of two but it isn't on 32-bit builds. Fixes: 08413a81b93dc537fb0c34327ad162f07e8c3427 Reviewed-by: Kenneth Graunke <kenneth@whitecape.org> Cc: mesa-stable@lists.freedesktop.org
