This reverts commit a39ad18593.

The commit aims to address "missing" -L/foo/bar during linking stage. At
the same time it doesn't add the -L and yet the LLVM_LDFLAGS [which
provide -L/foo/bar] are already used throughout.

Seems like something pretty unique (broken?) on my end. Since the commit
introduces issues (due to the missing -L) revert until we get to the
root of it (PEBKAC or a genuine issue).

I'm leaving num_out_sgpr around since it's not in a fast path, and besides
the compiler should be able to optimize it away easily. The alternative
with #if/#endif would be extremely ugly.

This reverts commit 25cc889004aad6d1cab9edd76db898658e347b97, though
since the code has changed, it was applied manually.

The intent of moving blocking from SwapBuffers to get_back_bo, was to
avoid unnecessary triple-buffering by ensuring that the compositor had
fully processed the previous frame before we started rendering. This
means that the only time we would have to resort to triple-buffering
would be when the buffer is directly scanned out, thus saving an extra
buffer for composition anyway.

The 'repaint window' changes introduced in Weston since then, however,
have narrowed the window of time between the frame event being sent and
the repaint loop needing to conclude, to 7ms by default, in order to
reduce latency. This means however that blocking in get_back_bo gives a
maximum of 7ms for the entire GL submission to begin and complete.

Not only this, but if a client is using buffer_age to avoid full
repaints, the buffer-age request will stall in get_back_bo until the
frame callback completes, meaning that the client cannot even calculate
the repaint area before the 7ms window.

The combination of the two meant that WebKit-GTK+ was failing to
achieve full framerate on a Minnowboard, due to spending a great deal of
its time attempting to query the age of the next buffer before redraw.

Revert to the previous behaviour of allowing rendering to begin but
delaying SwapBuffers, unless and until we can find a more gentle
behaviour.

Until now were validating in/out blocks by listing the inputs in the
consumer stage and then, for each output of the producer, we checked that
it was a match if it was consumed. This method does not catch the case
where the consumer has an input that is not present as an output in the
producer stage, because it only generates link errors for outputs present
in the producer stage that don't match the inputs in the consumer stage.
The current method does catch the case were an output from the producer
stage is not consumed, which is irrelevant and is ignored.

By reversing the way we do this, we can detect this situation, so this
patch lists the outputs of the producer stage and then validates inputs
of the consumer stage against them. If we see an input in the consumer
for which there is no associated output in the producer, we produce a
link error.

The only exception to this is the special built-in input block gl_in[],
since this is implicitly generated for geometry and tessellation stages,
but we don't generate it if the producer stage does not write to any of
the pre-defined outputs (for example, if the vertex shader does not write
to gl_Position, etc). Since writing to these is not mandatory, do not
produce a link error in that case. There is a CTS tessellation test
(GL45-CTS.tessellation_shader.program_object_properties) that has an
empty vertex shader (so it does not produce gl_in[]) and would fail to
link if we don't do this.

This fixes the following dEQP test:

Our previous fence implementation was very simple.  Fences had two states:
signaled and unsignaled.  However, this didn't properly handle all of the
edge-cases that we need to handle.  In order to handle the case where the
client calls vkGetFenceStatus on a fence that has not yet been submitted
via vkQueueSubmit, we need a three-status system.  In order to handle the
case where the client calls vkWaitForFences on fences which have not yet
been submitted, we need more complex logic and a condition variable.  It's
rather annoying but, so long as the client doesn't do that, we should still
hit the fast path and use i915_gem_wait to do all our waiting.

Instead of packing varyings into vec4's, keep track of how many
components each slot uses and create varyings with matching types. This
ensures that we don't end up using more components than the orginal
shader, which is especially important for geometry shader output limits.

Jonas Pfeil noticed that we were putting passthrough tlb_z writes early in
the shader, despite QIR and QPU scheduling both trying to delay scoreboard
locking for as long as possible.

The problem was that when trying to pair up QPU instructions, at some
point the passthrough tlb_z would be the last one available and it would
get paired, even if the other half would open up other instructions to be
scheduled and we could have paired tlb_z with something later in the
program.  Also, since passthrough z is just a mov, it pairs up really
easily.

The proper fix would probably be to flip the order of scheduling
instructions so we went from bottom to top (also relevant for branch delay
slot scheduling).

However, we can do a quick fix here to just not schedule a TLB lock until
there's nothing but TLB left in the program, at a slight instruction cost
(est .61% cycle count in shader-db) but a major fragment shader
parallelism win.

glmark2 results:
  texture:texture-filter=linear: +1.24481% +/- 0.626117% (n=15)
  bump:bump-render=height: 1.24991% +/- 0.154793% (n=136,133 -- screensaver
    outliers removed)

It's much better to just skip the draw call entirely.  Getting this
information out of register allocation will also be useful for
implementing threaded fragment shaders, which will need to retry
non-threaded if RA fails.

We had missed a bit of errata - PS scratch needs to be computed as if

Note that Skylake GT1-3 already worked because we allocated 64 * 9
(trying to use a value that would work on GT4, with 9 subslices),
and the actual required values were 64 * 4 or 64 * 8.  However, all
others (Skylake GT4, Broxton, and Kabylake GT1-4) underallocated,
which can lead to scratch writes trashing random process memory,
and rendering corruption or GPU hangs.

Fixes GPU hangs and rendering corruption on Skylake GT4 in shaders that

Vulkan has introduced the consept of .specVersion which can be used to
attribute changes of the said extension.

The current loader does not check the value, thus it have gone unnoticed
that the driver exposes an old version of the following extensions:

VK_KHR_xcb_surface        (Rev 6)
VK_KHR_xlib_surface       (Rev 6)
VK_KHR_wayland_surface    (Rev 5)
- Updated the surface create function to take a pCreateInfo structure

VK_KHR_swapchain          (Rev 68)
- Moved the "validity" include for vkAcquireNextImage to be in its proper
  place, after the prototype and list of parameters.
...

According to the documentation:

  * pname:specVersion is the version of this extension.
    It is an integer, incremented with backward compatible changes.

Based on the history of vk.xml the above (latest) revision has been
available since Vulkan 1.0 so even if they were any backwards
incompatible change(s) [as hinted by the revision log] those should be
safe.

I have diagnosed the failures, but I'm not sure whether we or the

    } x;

    void main()
    {
        x.f = x.f;
    }

The test then queries that x is referenced by that shader stage.  We
eliminate the assignment of x.f to itself, and that removes the last
reference to x.  We report that x is not referenced, and the test fails.
I do not know whether or not we are allowed to eliminate that assignment
of x.f to itself.

After discussions with the OpenGL ES group in Khronos, we believe that
Mesa's behavior is correct.  I will provide patches to the CTS tests
