Commit e1af20f18a86f52a9640faf2d4ff8a71b0a4fa9b changed the shader_info
from being embedded into being just a pointer. The idea was that
sharing the shader_info between NIR and GLSL would be easier if it were
a pointer pointing to the same shader_info struct. This, however, has
caused a few problems:
1) There are many things which generate NIR without GLSL. This means
we have to support both NIR shaders which come from GLSL and ones
that don't and need to have an info elsewhere.
2) The solution to (1) raises all sorts of ownership issues which have
to be resolved with ralloc_parent checks.
3) Ever since 00620782c92100d77c660f9783504c6d80fa1d58, we've been
using nir_gather_info to fill out the final shader_info. Thanks to
cloning and the above ownership issues, the nir_shader::info may not
point back to the gl_shader anymore and so we have to do a copy of
the shader_info from NIR back to GLSL anyway.
All of these issues go away if we just embed the shader_info in the
nir_shader. There's a little downside of having to copy it back after
calling nir_gather_info but, as explained above, we have to do that
anyway.

This isn't necessary yet but I'd like to use the range in
some future patches.

Use push descriptors instead of temp descriptor sets.

Most trace points happen after an operation, so add a trace point
at the start of the command buffer.
Furthermore, add one after a CmdUpdateBuffer using CP_DMA as that
didn't emit one yet.

Need to flush before updating the buffer to ensure that the copy is
ordered after previous accesses (assuming the app has performed the
appropriate barriers).
This fixes potential issues due to draws prior to an update reading
the new buffer content, despite having the necessary barriers between
them.

This just keeps popping up minor problems and regressions we should
revisit in a more sustainable manner later.
This also reverts:
Revert "radv: query cmds should mark a cmd buffer as having draws."
Revert "radv: also fixup event emission to not get culled."
This reverts commit d1640e79328af4a63c056e3ccab299a3bffbede7.
This reverts commit 8b47b97215af7157bc15676167cab73aa5a61a76.
This reverts commit b4b19afebeac84ddce3f1f8b7ffe0da6474fe29a.

If a buffer is just full of flushes we flush things on command
buffer submission, so don't bother submitting these.
This will reduce some CPU overhead on dota2, which submits a fair
few command streams that don't end up drawing anything.
v2: reorganise loop to count first then malloc,
rename some vars (Bas)

I just noticed the new vulkan headers changed a prototype,
so I've decided to import them and fix the drivers to use the
new API.

When restoring something from shader cache we won't have and don't
want to create a nir_shader this change detaches the two.
There are other advantages such as being able to reuse the
shader info populated by GLSL IR.

This squashes all the radv development up until now into
one for merging.
History can be found:
https://github.com/airlied/mesa/tree/semi-interesting
This requires llvm 3.9 and is in no way considered
a conformant vulkan implementation. It can run a number
of vulkan applications, and supports all GPUs using
the amdgpu kernel driver.
Thanks to Intel for providing anv and spirv->nir,
and Emil Velikov for reviewing build integration.
