Nouveau does not currently have logic to implement this as a library
function. Even though such a library could be written, there's no big
advantage to do it that way for now given that int64 is a very uncommon
use-case. Allow a driver to expose INT64 without supporting division and
modulo operations.

Make the cap consistent with PIPE_CAP_INT64.
Aside from the hypothetical case of using draw for vertex shaders (and
actually caring about doubles...), every implementation supports doubles
either nowhere or everywhere.
Also, st/mesa didn't even check the cap correctly in all supported
shader stages.
While at it, add a missing LLVM version check for 64-bit integers in
radeonsi. This is conservative: judging by the log, LLVM 3.8 might be
sufficient, but there are probably bugs that have been fixed since then.

Drivers that support this benefit by saving one lowering pass in the
GLSL-to-TGSI conversion.
radeonsi already supports this because all outputs are stored in temporary
variables before the export (except for TCS outputs, which have always
been readable in TGSI anyway due to their special semantics).

This allows the driver to signal that it can't handle random
interleaving of attributes across buffers. This is required for
ARB_transform_feedback3, and it's initialized to whatever the previous
value of PIPE_CAP_STREAM_OUTPUT_PAUSE_RESUME was except for nv50 where
it is disabled. Note that the proprietary drivers never expose
ARB_transform_feedback3 on any GT21x's (where nouveau previously did),
and after some effort I was unable to get it to work.

Some hardware can't render to color/depth buffers of mixed bitness. When
that happens a fallback has to happen, but this allows the driver to
express that this isn't an optimal scenario. The purpose of this is to
remove such fbconfigs from the GLX/EGL config list.

Some hardware supports primitive restart on patch primitives, and other
hardware does not. Modern GL and ES include a query for this feature;
adding a capability bit will allow us to answer it.
As far as I know, AMD hardware does not support this feature, while
NVIDIA and Intel hardware does. However, most Gallium drivers do not
appear to support tessellation shaders yet. So, I've enabled it for
nvc0 and disabled it everywhere else.

Add PIPE_CAP to determine if the GL extension
'GL_ARB_framebuffer_no_attachments' shall be
supported.
The driver is required to support 'PIPE_FORMAT_NONE'
via its 'is_format_supported()' callback in order
to determine the MSAA modes the hardware supports so
that values requested from the application using
'GL_ARB_framebuffer_no_attachments' may be quantized
to what the hardware expects.
V.2:
Fix doc for a more detailed description of the PIPE_CAP
and the corresponding GL constant.
V.3:
Renamed and repurposed once again.

For radeonsi, native and TGSI use different compilers and this results
in different limits for different IR's.
The set we strictly need for radeonsi is only the MAX_BLOCK_SIZE
and MAX_THREADS_PER_BLOCK params, but I added a few others as shader
related that seemed like they would also typically depend on the
compiler.
