instead the binding table offset (relative to surface state base address)
provided by the user is used verbatim.

We're about to start passing other things in as a sort of "VS header" for
vertex shaders and we need a place to put them. Since we want the instance
id to be one of them, it makes sense to have one vec4 that's either VUE
header or VS header. Always uploading some handy zeros makes the code a
bit simpler.

Depending on how the driver using blorp implements its shader caching,
there is a small chance of shader collisions due to identical keys between
blit and clear programs. Adding a small shader type at the top of the key
alleviates this problem.

At least on Sky Lake, after emitting 3DSTATE_CONSTANT_*, you are required
to re-emit the 3DSTATE_BINDING_TABLE_POINTERS packet for the corresponding
stage. If you don't, double-buffering may fail and you may get the wrong
constants. It turns out that you need to do this even if you have no push
constants to speak of or else the next 3DSTATE_CONSTANT packet you emit for
that stage may not work correctly.

Previously, we were creating the shader with a NULL ralloc context and then
trusting in blorp_compile_fs to clean it up. The only problem was that
blorp_compile_fs didn't clean up its context properly so we were leaking.
When I went to fix that, I realized that it couldn't because it has to
return the shader binary which is allocated off of that context and used by
the caller. The solution is to make blorp_compile_fs take a ralloc
context, allocate the nir_shaders directly off that context, and clean it
all up in whatever function creates the shader and calls blorp_compile_fs.

With dealing with rectangles in compressed images, you can have a width or
height that isn't a multiple of the corresponding compression block
dimension but only if that edge of your rectangle is on the edge of the
image. When we call convert_to_single_slice, it creates an 2-D image and a
set of tile offsets into that image. When detecting the right-edge and
bottom-edge cases, we weren't including the tile offsets so the assert
would misfire. This caused crashes in a few UE4 demos

Here brw_setup_vue_interpolation() is rewritten not to use the InterpQualifier
array in gl_fragment_program which will allow us to remove it.
This change also makes the code which is only used by gen4/5 more self contained
as it now has its own gen5_fragment_program struct rather than storing the map
in brw_context. This means the interpolation map will only get processed once
and will get stored in the in memory cache rather than being processed everytime
the fs changes.
Also by calling this from the fs compile code rather than from the upload code
and using the interpolation assigned there we can get rid of the
BRW_NEW_INTERPOLATION_MAP flag.
It might not seem ideal to add a gen5_fragment_program struct however by the end
of this series we will have gotten rid of all the brw_{shader_stage}_program
structs and replaced them with a generic brw_program struct so there will only
be two program structs which is better than what we have now.
V2: Don't remove BRW_NEW_INTERPOLATION_MAP from dirty_bit_map until the following
patch to fix build error.
V3 - Suggestions by Jason:
- name struct gen4_fragment_program rather than gen5_fragment_program
- don't use enum with memset()
- create interp mode set helper and simplify logic to call it
- add assert when calling function to show prog will never be NULL for
gen4/5 i.e. no Vulkan

In Vulkan, we want to be able to use blorp to perform clears inside of a
render pass. If blorp stomps the depth/stencil buffers packets then we'll
have to re-emit them. This gets tricky when secondary command buffers get
involved. Instead, we'll simply guarantee that the depth and stencil
buffers we pass to blorp (if any) match those already set in the hardware.

This never mattered before because the only time we used blorp
depth/stencil only was to do HiZ operations on gen6-7. It may have worked
in that case (and maybe it didn't) but slow depth clears actually do depth
rendering so they need a valid render target.

The Vulkan driver sets 3DSTATE_DRAWING_RECTANGLE once to MAX_INT x MAX_INT
at the GPU initialization time and never sets it again. The GL driver sets
it every time the framebuffer changes. Originally, blorp set it to the
size of the drawing area but meant we had to set it back in the Vulkan
driver. Instead, we can easily just do that in the GL driver's blorp_exec
implementation and not set it in blorp core.

The original blorp_alloc_binding_table helper was supposed to return the
binding table offset and map along with the surface state maps. This isn't
quite what we want, however. What we really want is the binding table
offsets, surface state offsets, and surface state maps. In the GL driver,
the binding table map *is* an array of surface state offsets. However, in
Vulkan, this isn't quite true as the entries in the binding table are
surface state offsets combined with another binding table block offset.

When Ivy Bridge introduced array multisampling, someone made the decision
to do lots of stuff throughout the driver in terms of physical array layers
rather than logical array layers. In ISL, we use logical array layers most
of the time and it really makes no sense to use physical array layers in
the blorp API. Every time someone passes physical array layers into blorp
for an array multisampled surface, they're always divisible by the number
of samples and we divide right away.
Eventually, I'd like to rework most of the GL driver internals to use
logical array layers but that's going to be a big project and will probably
happen as part of the ISL conversion. For now, we'll do the conversion in
brw_blorp and let blorp just use the logical layers.
