commit 7c8dfa78b98a12c1c5 (i965/draw: Use the real size for vertex
buffers) changed how we programmed the VERTEX_BUFFER_STATE size field.
Previously, we programmed it to the size of the actual underlying BO,
which is page-aligned, and potentially much larger than the GL buffer
object. This violated the ARB_robust_buffer_access spec.
With that change, we started programming it based on the range of data
we expect the draw call to actually access - which is based on the
min_index and max_index information provided to glDrawRangeElements().
Unfortunately, applications often provide inaccurate range information
to glDrawRangeElements(). For example, all the Unreal demos appear to
draw using a range of [0, 3] when the index buffer's actual index range
is [0, 5]. Such results are undefined, and we are absolutely allowed
to restrict access to the range they specified. However, the failure
mode is usually that nothing draws, or misrendering with wild geometry,
which is kind of bad for a common mistake. And people tend to assume
the range information isn't that important when data is in VBOs.
There's no real advantage, either. ARB_robust_buffer_access only
requires us to restrict access to the GL buffer object size, not
the range of data we think they should access. Doing that allows
buggy applications to still function. (Note that we still use this
information for busy-tracking, so if they try to overwrite the data
with glBufferSubData, they'll still hit a bug.) This seems to be
safer.
We may want to provide the more strict range as a debug option,
or scan the VBO and warn against bogus glDrawRangeElements in
debug contexts. That can be done as a later patch, though.
Makes Unreal demos draw again.

The stated bug describes a scenario in which a post sync write operation for
depth or timestamp can be ignored. There are two workarounds suggested, the
first and easier is to simply do a cs stall when we do these type of writes.
The second option is to do a PIPE_CONTROL flush after the post sync but before
the data is required.
Generally, I believe the data written out is consumed by the application on the
CPU side and so doing the easier of the two is ideal. Furthermore, these queries
aren't tremendously common in the perf sensitive apps I have looked at. However,
there could be cases where a shader stage might directly consume the data, and
as a result option 2 may be desirable.
This patch goes with the easier solution for now.

Using more than 1 wave per threadgroup does increase performance
generally. Not using too many patches per threadgroup also
increases performance. Both catalyst and amdgpu-pro seem to
use 40 patches as their maximum, but I haven't really seen
any performance increase from limiting the number of patches
to 40 instead of 64.
Note that the trick where we overlap the input and output LDS
does not work anymore as the insertion of the tess factors
changes the patch stride.
v2: - Add comment about LDS assumptions.
- Add constant for buffer size.
- Fix code style.
v3: - Correct limits for not splitting patches between waves.
- Set max num_patches to 40 as in the proprietary driver.

We always try to use 4-component loads, as LLVM does not combine loads
and they bypass the L1 cache.
We can't use a similar strategy for stores and this is especially
notable with the tess factors, as they are often set with separate
MOV's per component in the TGSI.
We keep storing to LDS and the LDS space, so we can load the outputs
later, either due to the shader, of for wrting the tess factors.

We need to copy the VS outputs to memory. I decided to do this
using a shader key, as the value depends on other shaders.
I also switch the fixed function TCS over to monolithic, as
otherwisze many of the user SGPR's need to be passed to the
epilog, which increases register pressure, or complexity to
avoid that. The main body of the fixed function TCS is not
that interesting to precompile anyway, since we do it on
demand and it is very small.

Instead of creating a memory area per patch and per vertex, we put
the same attribute of every vertex & patch together. Most loads
and stores access the same attribute across all lanes, only for
different patches and vertices.
For the TCS this results in tightly packed data for 4-component
stores.
For the TES this is not the case as within a patch the loads
often also access the same vertex. However if there are < 4
vertices/patch, this still results in a reduction of the number
of cache lines. In the LDS situation we only do better than worst
case if the data per patch < 64 bytes, which due to the
tessellation factors is pretty much never.
We do not use hardware swizzling for this. It would slightly reduce
the number of executed VALU instructions, but I had issues with
increased wait times that I haven't been able to solve yet.
Furthermore, the tbuffer_store intrinsic does not support both
VGPR offset and an index, so we have a problem storing
indirectly indexed outputs. This can be solved by temporarily
storing arrays in LDS and then copying them, but I don't think
that is worth the effort. The difference in VALU cycles
hardware swizzling gives is about 0.2% of total busy cycles.
That is without handling the array case.
I chose for attributes instead of components as they are often
accessed together, and the software swizzling takes VALU cycles
for calculating offsets.
v2: - Rename functions to get_tcs_tes_buffer_address.
- multiply by 16 as late as possible.
- Use tgsi_full_src_register_from_dst.

To read out MP perf counters we use a compute shader and need to upload
input data like a 64-bits addr used to store the values and a sequence
ID for synchronization. Currently, this input data is uploaded as user
uniforms which means that it's sticked to c0[], but if a compute shader
from a real application is used, monitoring those performance counters
will just overwrite some data and miserably crash.
Instead, sticking the 64-bits addr and the sequence into the driver
constant buffer seems like much better and will allow to monitor
counters with GL 4.3 apps.
Tested on GF119 and GK110, but should not hurt anything on GK104.
