The current way of handling groups doesn't seem to be able to handle
MI_LOAD_REGISTER_* with more than one register. This change reworks
the way we handle groups by building a traversal list on loading the
GENXML files.

Let's say you have

Instruction {
  Field0
  Field1
  Field2
  Group0 (count=2) {
    Field0-0
    Field0-1
  }
  Group1 (count=4) {
    Field1-0
    Field1-1
  }
}

We build of linked on load that goes :

Instruction -> Group0 -> Group1

All of those are gen_group structures, making the traversal trivial.
We just need to iterate groups for the right number of timers (count
field in genxml).

The more fancy case is when you have only a single group of unknown
size (count=0). In that case we keep on reading that group for as long
as we're within the DWordLength of that instruction.

tgsi/scan: fix scanning fragment shaders with PrimID and Position/Face

Not relevant to radeonsi, because Position/Face are system values
with radeonsi, while this codepath is for drivers where Position and
Face are ordinary inputs.

i965: Finalize miptrees before prepare_texture

In order to do resolves for texture views with different formats, we
need intel_texture_object::_Format to be valid.  Calling
intel_finalize_mipmap_tree can safely be done multiple times in a row
and should be a fairly cheap operation.

st/mesa: don't load cached TGSI shaders on demand

This fixes a performance issue with the shader cache that delayed Gallium
shader create calls until draw calls.

I'd like this in stable, but it's not a showstopper.

radv: prepare fmask surface creation

The old code copied over all the surface info from the image
surface, we only want some bits of it, and to modify the flags.

This prevents a regression in dEQP-VK.api.copy_and_blit.resolve_image.*
and others in the subsequent switch to ac_compute_surface.

v2:
- also disable opt4Space in radv_amdgpu_surface, so that we can
  apply this patch separately *before* switching to ac_compute_surface
  and hopefully avoid intermittent regressions (Nicolai)
