This implements support in radv and radeonsi for NIR deref instructions instead of deref chains.
It contains 4 parts: - patch 1 is a fixup for the initial series by Jason - Add support everywhere for instruction based derefs - Stop lowering them to deref chains (may need to be synchronized with other drivers and core nir code to keep things bisectable) - Remove support for deref chains.
