st/nine: Implement relative addressing for ps inputs

To implement the feature we copy the ps inputs to a temp array.
This is not optimal for performance, but it is the simplest solution.

This is a feature that is very very rarely used.

egl: Unify the EGLint/EGLAttrib paths in eglCreateSync* (v3)

Pre-patch, there were two code paths for parsing EGLSync attribute
lists: one path for old-style EGLint lists, used by eglCreateSyncKHR,
and another for new-style EGLAttrib lists, used by eglCreateSync (1.5)
and eglCreateSync64 (EGL_KHR_cl_event2).

There were two attrib_list parsing functions,
  _eglParseSyncAttribList(_EGLSync *sync, const EGLint *attrib_list)
  _eglParseSyncAttribList64(_EGLSync *sync, const EGLattrib *attrib_list)
This patch unifies the two attrib_list parsing functions into one,
  _eglParseSyncAttribList(_EGLSync *sync, const EGLattrib *attrib_list)

Many internal EGLSync function signatures had *two* attrib_list
parameters to accomodate both code paths: one parameter was an EGLint
list and other an EGLAttrib list. At most one of the parameters was
allowed to be non-null.  This patch removes the `EGLint *attrib_list`
parameter, leaving only the `EGLAttrib *attrib_list` parameter, for all
internal EGLSync functions.

v2:
  - Consistently use condition (sizeof(int_list[0]) ==
    sizeof(attrib_list[0])). [for emil]
v3:
  - Don't double-unlock the display in eglCreateSyncKHR.

vc4: Fix perf debug formatting on partial Z/S clear.

vc4: Drop destination register when it's unused.

This slightly reduces instructions on shader-db, but I think it's just
perturbing register allocation -- the allocator should have always
trivially colored these nodes, before.  This commit is just to make QIR
code failing more intelligible when register allocation fails.

vc4: Fix live intervals analysis for screening defs in if statements.

If a conditional assignment is only conditioned on the exec mask, that's
still screening off the value in the executed channels (and, since we're
not storing to the unexcuted channels, we don't care what's in there).

Fixes a bunch of extra register pressure on Processing's Ribbons demo,
which is failing to allocate.

vc4: Fix simulator when more than one vc4_screen is opened.

We would assertion fail in setting up the simulator the second time
around.  This at least postpones the assertion failure until we've closed
all of the first set of screens and started opening a new set.

vc4: Fix assertion fails from trying to cast non-ALU instrs to ALU.

Fixes 100 piglit tests since the assertions were added to nir.h.  What's
amazing is that these tests used to pass, even when casting garbage.

anv/cmd_buffer: Don't call set_subpass in a secondary

Initially, we had intended set_subpass to be an interesting function that
did whatever (presumably a lot) setup we needed for a subpass.  In reality,
it just sets a pointer and a dirty bit and then emits depth and stencil
state.  When we call BeginCommandBuffer on a secondary, there's no point in
setting depth and stencil state since it will already be set by the
primary.  Instead, the only thing we need to do at the start of a secondary
is set the subpass pointer and the dirty bit.

anv/wsi: Advertise UNORM formats as well as sRGB

Because WSI images are created with VkImageCreateInfo::flags explicitly set
to 0, they don't ever have the VK_IMAGE_CREATE_MUTABLE_FORMAT_BIT set.
This means that you can't create an image view of it with a different
format so applications can't render directly in sRGB (without automatic
encoding) unless we actually advertise UNORM formats.  There are a lot of
applications that want to do their own sRGB conversion, so we should allow
for that.  We do, however, make UNORM come after sRGB in the list so that
the default for dumb apps that just grab the first thing is to render in
linear and let the sRGB conversion happen automatically.

st/mesa: optimize pipe_sampler_view validation

Before, st_get_texture_sampler_view_from_stobj() did a lot of work to
check if the texture parameters matched the sampler view (format,
swizzle, min/max lod, first/last layer, etc).  We did this every time
we validated the texture state.

Now, we use a ctx->Driver.TexParameter() callback and a couple other
checks to proactively release texture views when we know that
view-related parameters have changed.  Then, the validation step is
simplified:
- Search the texture's list of sampler views (just match the context).
- If found, we're done.
- Else, create a new sampler view.

There will never be old, out-of-date sampler views attached to texture
objects that we have to test.

Most apps create textures and set the texture parameters once.  This
make sampler view validation much cheaper for that case.

Note that the old texture/sampler comparison code has been converted
into a set of assertions to verify that the sampler view is in fact
consistent with the texture parameters.  This should help to spot any
potential regressions.
