swr: rework resource layout and surface setup
This is a bit of a mega-commit, but unfortunately there's no great way
to break this up since a lot of different pieces have to match up. Here
we do the following:
- change surface layout to match swr's Load/StoreTile expectations
- fix sampler settings to respect all sampler view parameters
- fix stencil sampling to read from secondary resource
- respect pipe surface format, level, and layer settings
- fix resource map/unmap based on the new layout logic
- fix resource map/unmap to copy proper parts of stencil values in and
out of the matching depth texture
These fix a massive quantity of piglits, including all the
tex-miplevel-selection ones.
Note that the swr native miptree layout isn't extremely space-efficient,
and we end up using it for all textures, not just the renderable ones. A
back-of-the-envelope calculation suggests about 10%-25% increased memory
usage for miptrees, depending on the number of LODs. Single-LOD textures
should be unaffected.
There are a handful of regressions as a result of this change:
- Some textureGrad tests, these failures match llvmpipe. (There are
debug settings allowing improved gallivm sampling accurancy.)
- Some layered clearing tests as swr doesn't currently support that. It
was getting lucky before because enough other things were broken.
