This commit, out of necessity, makes a number of changes at once:
1) Changes intel_mipmap_tree to store the clear color for both color
and depth as an isl_color_value.
2) Changes the depth/stencil emit code to do the format conversion of
the depth clear value on Haswell and earlier instead of pulling a
uint32_t directly from the miptree.
3) Changes ISL's depth/stencil emit code to perform the format
conversion of the depth clear value on Haswell and earlier instead
of assuming that the depth value in the float is pre-converted.
4) Changes blorp to pass the depth value through as a float.
5) Changes the Vulkan driver to pass the depth value to blorp as a
float rather than a uint.

Due to complications with things such as URB setup on gen4-5, it's
easier to keep gen4 support in blorp completely internal to i965. This
makes things a bit awkward because that means there's a file in i965
that includes blorp_priv.h but it's either that or have a file in blorp
that includes brw_context.h.

We need to emit BLEND_STATE, which size is 1 + 2 * nr_draw_buffers
dwords (on gen8+), but the BLEND_STATE struct length is always 17. By
marking it size 1, which is actually the size of the struct minus the
BLEND_STATE_ENTRY's, we can emit a BLEND_STATE of variable number of
entries.
For gen6 and gen7 we set length to 0, since it only contains
BLEND_STATE_ENTRY's, and no other data.
With this change, we also change the code for blorp and anv to emit only
the needed BLEND_STATE_ENTRY's, instead of always emitting 16 dwords on
gen6-7 and 17 dwords on gen8+.
v2:
- Use designated initializers on blorp and remove 0 from
initialization (Jason)
- Default entries to disabled on Vulkan (Jason)
- Rebase code.

Most of the time we use macros that handle this situation transparently,
but there are some cases were we need to handle this explicitly.
This patch makes sure we don't crash, notice that error handling takes
place in the function that actually failed the allocation,
anv_batch_emit_dwords(), which will set the status field of the batch
so it can be used at a later moment to report the error to the user.
v2:
- Not crashing is not good enough, we need to keep track of the error
(Topi, Jason). Iago: now that we track errors in the batch, this
is being handled.
- Added guards in a few more places that needed it (Iago)
v3:
- Check result of anv_batch_emitn() for NULL before calling memset()
in emit_vertex_input() (Topi)

We'll be switching to layout-transition based resolves which can occur
outside of a render pass. Add this sequence to BLORP, as using BLORP
will enable emitting depth stencil state outside of a render pass (among
other benefits). The depth buffer extent is ignored to enable eventual
usage in VkCmdClearAttachments().

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.

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

The Vulkan driver sets 3DSTATE_DRAWING_RECTANGLE once to MAX_INT x MAX_INT

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

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.

While it can be useful, the field has substantial limtations. In
particular, the bittom 2 or 3 bits is missing so your offset always has to
be a multiple of 4 or 8. While surface alignments usually work out to make
this ok, when you start trying to fake compressed surfaces as uncompressed
(which we will want to do) this falls apart. The easiest solution is to
simply align all offsets to a tile boundary and munge the regions we're
copying to account for the intratile offset.
