Some GPUs (e.g. GK20A, GM20B) do not embed VRAM of their own and use
the system memory as a backend instead. For such systems, allocating
objects in VRAM results in errors since the kernel will not allow
VRAM objects allocations.
This patch adds a vram_domain member to struct nouveau_screen that can
optionally be initialized to an alternative domain to use for VRAM
allocations. If left untouched, NOUVEAU_BO_VRAM will be used for
systems that embed VRAM, and NOUVEAU_BO_GART will be used for VRAM-less
systems.
Code that uses GPU objects is then expected to use the NV_VRAM_DOMAIN()
macro in place of NOUVEAU_BO_VRAM to ensure correct behavior on
VRAM-less chips.

For query_levels, we generate a getinfo with writemask of (z), which RA
will consider as size==3. But we were still generating four fanouts.
Which meant that RA would see it as two different register classes,
depending on the path to definer. Ie. on the getinfo instruction itself
it would see size==3, but when chasing back through the fanouts it would
see size==4.
Easiest way to solve that is to just generate the chain of neighboring
fanouts to have the correct size in the first place.
Note: we may eventually want split_dest() to take start/end or wrmask
instead, since really we only need size==1. But RA is not clever enough
for that, query_levels is not that common, and the other two registers
that get allocated are never used so those register slots can be
immediately re-used. So bunch of work for probably no real gain.

We get this information from NIR (which gets it from sview decl in tgsi
when translating from tgsi), so no need to maintain shader variants for
this.

This shuffles things around to allow the shader to have multiple basic
blocks. We drop the entire CFG structure from nir and just preserve the
blocks. At scheduling we know whether to schedule conditional branches
or unconditional jumps at the end of the block based on the # of block
successors. (Dropping jumps to the following instruction, etc.)
One slight complication is that variables (load_var/store_var, ie.
arrays) are not in SSA form, so we have to figure out where to put the
phi's ourself. For this, we use the predecessor set information from
nir_block. (We could perhaps use NIR's dominance frontier information
to help with this?)

These belong in the shader, rather than the block. Mostly a lot of
churn and nothing too interesting. But splitting this out from the
rest of ir3_block reshuffling to cut down the noise in the later

Use a more standard priority-queue based scheduling algo. It is simpler
and will make things easier once we have multiple basic blocks and flow

Use standard list_head double-linked list and related iterators,
helpers, etc, rather than weird combo of instruction array and next
pointers depending on stage. Now block has an instrs_list. In
certain stages where we want to remove and re-add to the blocks list
we just use list_replace() to copy the list to a new list_head.

Freedreno needs sampler type information to deal with int/uint textures.
To accomplish this, start creating sampler-view declarations, as
suggested here:
http://lists.freedesktop.org/archives/mesa-dev/2014-November/071583.html
create a sampler-view with index matching the sampler, to encode the
texture type (ie. SINT/UINT/FLOAT). Ie:
DCL SVIEW[n], 2D, UINT
DCL SAMP[n]
TEX OUT[1], IN[1], SAMP[n]
For tgsi texture instructions which do not take an explicit SVIEW
argument, the SVIEW index is implied by the SAMP index.

This was a hack as part of debugging some glamor-on-GLES2 behavior that
ended up being an xserver bug. I suspect we can just flip this extension
on for GLES2, but the spec says it requires 3.1.
We need to make sure that when we store the aligned box, we've got
initialized contents in the border. We could potentially just load the
border area, but for now let's get text rendering working in X (and fix
the GL_TEXTURE_2D errors in piglit's texsubimage test and
gl-2.1-pbo/test_tex_image)
Being a parameter-like state, we may want to get rid of
ilo_state_vertex_buffer_info or ilo_state_vertex_buffer eventually. But we
want them now as they are how we do cross-validation right now.
3DSTATE_VF_INSTANCING specifies instancing enable and step rate. They are
specified along with 3DSTATE_VERTEX_BUFFERS instead prior to Gen8. Both
commands are added.
3DSTATE_VF specifies cut index enable and cut index. Cut index enable is
specified in 3DSTATE_INDEX_BUFFER instead prior to Gen7.5. Both commands are
added.
ilo_shader.c: In function ‘ilo_shader_select_kernel_sbe’:

The original code meant to do this, but was only checking num_samples == 1 to
figure out if a surface was fast clear capable. However, we can allocate single
sample miptrees with num_samples == 0 (when it's an internally created buffer).
This fixes a bunch of the piglit tests on gen8. Other gens should have been
fine.
Here is the order of events that allowed this to slip through:
t0: I wrote halign patches and tested them. These alignment assertions are for
gen8 fast clear surfaces, basically.
t1: I pushed bogus perf patch which made fast clears never happen
t2: Reworked halign patches based on Chad's feedback and introduced the bug this
patch fixes.
t2.5: I tested reworked patches, but assertion wasn't hit because of t1.
t3. Matt fixed issue in t1 which made fast clears happen here:

If the driver says PIPE_CAP_VERTEX_ELEMENT_SRC_OFFSET_4BYTE_ALIGNED_ONLY=1,
the driver should never receive a pipe_vertex_element::src_offset value
that's not a multiple of four. But the vbuf code wasn't actually adjusting
the src_offset value when creating the vertex element state object.
We just need to align the src_offset values put in the driver_attribs[]
array.
