[Mesa-dev] i965: Prep work for transitioning to ISL

[Topi Pohjolainen]

Here are miscellanious "little" things now and there making
the actual transition cleaner/simpler.

These sit on top of Jason's ccs-modifiers.

Topi Pohjolainen (16):
  i965/miptree: Set refcount before failing via _release()
  i965/miptree: Use > 1 instead of > 0 to check for multisampling
  i965: Mark read-only args as const in intel_miptree_supports_hiz()
  i965/tex: Use offset helper instead of accessing table directly
  i965: Make irb::mt_layer logical instead of physical
  i965/miptree: Do not rely on msaa type to decide if aux is needed
  i965/miptree: Check for miptree_create() failures
  i965/wm: Use isl for determining vertical slice pitch
  i965/miptree: Stop setting total_width/height for existing bo
  i965/miptree: Add pitch override for imported buffer objects
  i965/miptree: Pass flags instead of explicit tiling to surface creator
  i965: Use offset helper in intel_readpixels_tiled_memcpy()
  i965/wm: Use level offsets directly
  intel/blorp/gen4: Drop cube map flag for single face copy
  i965: Refactor check for separate stencil
  i965/gen4: Set tile offsets to zero after depth rebase
