This looks like an evergreen specific feature, but with atomic
counters AMD have hw specific counters they use instead of operating
on buffers directly. These are separate to the buffer atomics,
so require different limits and code paths.
I've left the CAP for atomic type extensible in case someone
else has a variant on this sort of thing (freedreno maybe?)
and needs to change it.
This adds all the CAPs required to add support for those atomic
counters, along with a related CAP for limiting the number of
output resources.
I'd like to land this and the st patch then I can start to
upstream the evergreen support for these and other GL4.x features.
v2: drop the ATOMIC_COUNTER_MODE cap, just use the return
from the HW counters. If 0 we use the current mode.
v3: fix some rebase errors (Gert Wollny)

This patch makes use of the DRM_IOCTL_VC4_GEM_MADVISE ioctl to mark all
BOs placed in the mesa BO cache as purgeable so that the system can
reclaim this memory under memory pressure.
v2:
- Removed BOs from the cache when they've been purged by the kernel
- Check whether the madvise ioctl is supported or not before using it

If the DRM_VC4_GET_TILING ioctl isn't present then we can't tell
if a dmabuf bo is tiled or linear, so will always assume it's
linear.
By not advertising tiled formats in this situation we ensure the
assumption is correct.
This fixes a bug where most attempts to render a gl wayland client

X11 and GL compositor performance on VC4 has been terrible because of our
SHARED-usage buffers all being forced to linear. This swaps SHARED &&
!LINEAR buffers over to being tiled.
This is an expected win for all GL compositors during rendering (a full
copy of each shared texture per draw call), allows X11 to be used with
decent performance without a GL compositor, and improves X11 windowed
swapbuffers performance as well. It also halves the memory usage of
shared buffers that get textured from. The only cost should be idle
systems with a scanout-only buffer that isn't flagged as LINEAR, in which
case the memory bandwidth cost of scanout goes up ~25%.
This implements the EGL_EXT_image_dma_buf_import_modifiers extension,
supporting the VC4 T_TILED modifier.

advertisement (by daniels).

There's no reason we can't -- the mappings we expose are basically
equivalent to persistent/coherent, already.
Improves mesa-demos drawoverhead (no state change) performance by
5.21362% +/- 1.25078% (n=11).
This follows the model of imx (display) and etnaviv (render): pl111 is a
display-only device, so when asked to do GL for it, we see if we have a
vc4 renderer, make the vc4 screen, and have vc4 call back to pl111 to do
scanout allocations.
The difference from etnaviv is that we share the same BO between vc4 and
pl111, rather than having a vc4 bo and a pl11 bo and copies between the
two. The only mismatch between their requirements is that vc4 requires
4-pixel (at 32bpp) stride alignment, while pl111 requires that stride
match width. The kernel will reject any modesets to an incorrect stride,
so the 3D driver doesn't need to worry about that.

In the hardware we only get to declare 8 vertex elements (GLES2's
minimum), so we should be exposing that number here. Fixes an assertion
failure in piglit texrect-many, at the expense of various GL 2.0-ish
minmax tests now complaining that our count is too low.
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.

Looking at 2 of the 7 different shaders that were hurt (all of which were
