Nobody queries these and nobody sets them to anything useful,
the docs say TODO.
Drop them until a use appears.

Because vc4 can control the order that tiles are rasterized in, we can use
it to implement overlapping blits using normal drawing and
GL_ARB_texture_barrier, as long as we can tell the kernel what order to
render the tiles in.
This commit introduces the core gallium support, vc4 changes will follow.
v2: Fix on the simulator.
v3: Add the cap (disabled) to other drivers, add rst docs for the cap.
v4: Rebase on PIPE_CAP_TGSI_ANY_REG_AS_ADDRESS
v5: Drop vc4 changes from this commit, for clarity.

The driver was supposed to support this since way before the GL spec for it
existed, albeit it was apparently broken, so fix and enable it.

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.
v2: fix clover (Marek)

This enables gallium support for EGL_ANDROID_native_fence_sync, for
drivers which support PIPE_CAP_NATIVE_FENCE_FD.

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.

On 32 bits system, application memory is quite limited.
softpipe uses application memory. To help prevent memory
exhaustion, limit reported memory availability to 2GB.
Some gallium nine apps do check reported memory by allocating
resources until memory is full. Gallium nine refuses allocations
when 80% of the reported memory limit is used. This change
helps some apps to start.
