Supporting simd16 vertex shaders involves packing the output of the
fetch shader appropriately, especially the vertexID buffers that have to
be formatted in one simd16 register, needed by the VS.
As part of this support, we needed to remove the 2nd JitManager, since it
was not accounting for vector width correctly.
USE_SIMD16_SHADERS is also split into two defines. The additional
one (USE_SIMD16_VS) controls the width of the vertex shader (VS), while
the original one (USE_SIMD16_SHADERS) controls overall front end width.

This patch fixes piglit tex3d-maxsize by correcting 4 things:
The total_size calculation was using 32-bit math, therefore a >4GB
allocation request overflowed and was not returning false (unsupported).
Changed AlignedMalloc arguments from "unsigned int" to size_t, to handle
>4GB allocations.
Added error checking on texture allocations to fail gracefully.
Finally, temporarily decreased supported max texture size from 4GB to 2GB.
The gallivm texture-sampler needs some additional work to correctly handle
larger than 2GB textures (offsets to LLVMBuildGEP are signed).
I'm working on a follow-on patch to allow up to 4GB textures, as this is
useful in HPC visualization applications.
Fixes piglit tex3d-maxsize.
v2: Updated patch description to clarify ">4GB".

Remove allocation of > 2kbyte buffers into context memory in
swr_copy_to_scatch_space() (which is used to copy small vertex/index buffers
and shader constants to a scratch space to be used by the upcoming draw.)
Large shader constant allocations need to be done in the circular scratch
buffer instead of context memory, because their values persist across
render calls.
Also lower SCRATCH_SINGLE_ALLOCATION_LIMIT to 8k, since allocations of larger
buffers will get too large for the circular scratch space.

Accompanying patch "st/mesa: only try to create 1x msaa surfaces for
'fake' msaa" requires driver to report max_samples=1 to enable "fake"
msaa. Previously, 0 and 1 were treated equivalently in st_init_extensions()
and either could enable "fake" msaa.
This patch raises the swr default msaa_max_count from 0 to 1, so that
swr_is_format_supported will report max_samples=1.
Real msaa can still be enabled by exporting SWR_MSAA_MAX_COUNT with a
pow2 value between 2 and 16.
This patch is necessary to prevent an OpenSWR regression resulting from
the st/mesa patch.

If size of client memory copy is too large, don't copy. The draw will
access user-buffer directly and then block. This is faster and more
efficient than queuing many large client draws.
Applications that still use large client arrays benefit from this. VMD
is an example.
The threshold for this path defaults to 32KB. This value can be
overridden by setting environment variable SWR_CLIENT_COPY_LIMIT.
v2: Use #define for default value, rather than hard-coded constant.

This patch limits the number of items on the fence work queue (the
deferred deletion list) by submitting a sync fence when the queue size
exceeds a threshold. This initiates deferred deletion of all resources
on the list and decreases the total amount of memory held waiting for
"deferred deletion".
This resolves bug 101467 filed against swr for the piglit
streaming-texture-leak test. For those running on smaller memory
(16GB?) systems, this will prevent oom-killer.
Thus far, we have not seen any real world applications that exhibit
behavior like the streaming-texture-leak test; as any form of pipeline
flush will trigger the defer queue and properly free any retained
allocations. But, this addresses those as well.

v3: list piglit tests fixed by this patch. Fixed typo Tim pointed out.
v2: Reword commit message to more closely adhere to community
guidelines.
This patch moves msaa resolve down into core/StoreTiles where the
surface format conversion routines are available. The previous
"experimental" resolve was limited to 8-bit unsigned render targets.
This fixes a number of piglit msaa tests by adding resolve support for
all the render target formats we support.
Specifically:
layered-rendering/gl-layer-render: fail->pass
layered-rendering/gl-layer-render-storage: fail->pass
multisample-formats *[2,4,8,16] gl_arb_texture_rg: crash->pass
multisample-formats *[2,4,8,16] gl_ext_texture_snorm: crash->pass
multisample-formats *[2,4,8,16] gl_arb_texture_float: fail->pass
multisample-formats *[2,4,8,16] gl_arb_texture_rg-float: fail->pass
MSAA is still disabled by default, but can be enabled with
"export SWR_MSAA_MAX_COUNT=4" (1,2,4,8,16 are options)
The default is 0, which is disabled.
This patch improves the number of multisample-formats supported by swr,
and fixes several crashes currently in the 17.1 branch. Therefore, it
should be considered for inclusion in the 17.1 stable release. Being
disabled by default, it poses no risk to most users of swr.

This patch enables multisample antialiasing in the OpenSWR software renderer.
MSAA is a proof-of-concept/work-in-progress with bug fixes and performance
on the way. We wanted to get the changes out now to allow several customers
to begin experimenting with MSAA in a software renderer. So as not to
impact current customers, MSAA is turned off by default - previous
functionality and performance remain intact. It is easily enabled via
environment variables, as described below.
It has only been tested with the glx-lib winsys. The intention is to
enable other state-trackers, both Windows and Linux and more fully support
FBOs.
There are 2 environment variables that affect behavior:
* SWR_MSAA_FORCE_ENABLE - force MSAA on, for apps that are not designed
for MSAA... Beware, results will vary. This is mainly for testing.
* SWR_MSAA_MAX_SAMPLE_COUNT - sets maximum supported number of
samples (1,2,4,8,16), or 0 to disable MSAA altogether.
(The default is currently 0.)
