The sample mask is used even if msaa is not explicity enabled when we
have a framebuffer with multisampled surfaces. That's DX behavior and
what the Radeon drivers do. Not sure about other drivers at this point.

This API binds atomic buffers for all bound shaders (as per the
GL semantics).
This is needed to support cross shader hw atomic counters.

This adds support for a hw atomic counters to TGSI.
A new register file for storing atomic counters is added,
along with a new atomic counter semantic, along with docs
for both.
v2: drop semantic, move hw counter to backend,
Ilia pointed out SSO would have busted my plan, and he
was right.
v3: drop BUFFER decls. (Marek)
v3.1: minor fixups for whitespace, set ureg error
if we overflow the hw atomic limits. (nha)
v3.2: fix some docs inconsistencies (Ilia)

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)

These bits are intended to be used by the ddebug hang detection and are
named in analogy to the Vulkan stage bits (and the corresponding Radeon
pipeline event).
Hang detection needs fences on the granularity of individual commands,
which nothing else really covers. The closest alternative would have
been PIPE_QUERY_GPU_FINISHED, but (a) queries are a per-context object
and we really want a per-screen object, (b) queries don't offer a
wait with timeout, and (c) in any case, PIPE_QUERY_GPU_FINISHED is
meant to imply that GPU caches are flushed, which the new bits
explicitly aren't.

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 operation performed is all the same as LODQ, but with the usual
differences between dx10 and GL texture opcodes, that is separate resource
and sampler indices (plus result swizzling, and setting z/w channels
to zero).

The status quo is quite the mess:
1. tgsi_exec will do a per-channel computation, and store the dst[0]
result (significand) correctly for each channel. The dst[1] result
(exponent) will be written to the first bit set in the writemask.
So per-component calculation only works partially.
2. r600 will only do a single computation. It will replicate the
exponent but not the significand.
3. The docs pretend that there's per-component calculation, but even
get dst[0] and dst[1] confused.
4. Luckily, st_glsl_to_tgsi only ever emits single-component instructions,
and kind-of assumes that everything is replicated, generating this for
the dvec4 case:
DFRACEXP TEMP[0].xy, TEMP[1].x, CONST[0][0].xyxy
DFRACEXP TEMP[0].zw, TEMP[1].y, CONST[0][0].zwzw
DFRACEXP TEMP[2].xy, TEMP[1].z, CONST[0][1].xyxy
DFRACEXP TEMP[2].zw, TEMP[1].w, CONST[0][1].zwzw
Settle on the simplest behavior, which is single-component calculation
with replication, document it, and adjust tgsi_exec and r600.

Sourcing the exponent for the zw destination pair from Z is consistent
with both tgsi_exec and gallivm. In practice, st_glsl_to_tgsi always
generates per-channel instructions anyway.

To be able to properly distinguish between GL_ANY_SAMPLES_PASSED
and GL_ANY_SAMPLES_PASSED_CONSERVATIVE.
This patch goes through all drivers, having them treat the two
query types identically, except:
1. radeon incorrectly enabled conservative mode on
PIPE_QUERY_OCCLUSION_PREDICATE. We now do it correctly, only
on PIPE_QUERY_OCCLUSION_PREDICATE_CONSERVATIVE.
2. st/mesa uses the new query type.
