This is mostly a re-send of a patch series I've had floating around in one form or a while for quite some time. It's basically the same except that the original version was missing a work-around for Sandy Bridge. For a while, I wasn't really pushing to get it merged because I couldn't demonstrate any actual performance benifit from pushing arrays. However, with the Vulkan API, the concept of push constants is directly exposed to the user and we really need to be able to indirect on them. This series makes the FS backend 100% ready for indirect push constants; vec4 will take a little more work.
It's worth noting that we've been carying these patches around in our Vulkan driver for probably 3 or 4 months now and it's working great. For those that prefer to review on a branch: https://cgit.freedesktop.org/~jekstrand/mesa/log/?h=review/i965-uniforms I think Kristian has mostly reviewed these patches. However, he never sent any R-Bs to the list. I'd also like Ken or Matt to look at it from a design perspective.
