iris: Enable PIPE_CAP_CS_DERIVED_SYSTEM_VALUES_SUPPORTED
This avoids lowering of CS system values by GLSL (configured by state

need that in Iris.
Using it cause some unnecessary round trip between values, e.g.:
shader uses gl_LocalInvocationIndex, GLSL rewrites it in terms of
gl_LocalInvocationID, then driver rewrites those in terms of
gl_LocalInvocationIndex again. Copy propagation can make some of
those go away, but not all as seen below.

freedreno: add helper to uncompress UBWC resource
We'll need this for a few edge cases, like image/sampler view that uses
a format that UBWC does not support with a resource originally created
in a format that UBWC does support.
NOTE we *could* in some cases do an in-place uncompress. But that has
a couple potential sharp edges:
1) the uncompressed buffer could have different layout, ie. a5xx
with meta and pixel data of layers/levels interleaved.
2) if it comes mid-batch, it would force flush, or somehow fixing
up cmdstream for draws already emitted. But with the resource
shadowing approach we can rely on batch re-ordering to avoid
splitting things.. older draws see the older compressed version,
newer draws see the new uncompressed version of the rsc.

panfrost/midgard: Expose vec8/vec16 modes
Midgard ALUs can operate in one of four modes: vec2 64-bit, vec4 32-bit,
vec8 16-bit, or vec16 8-bit. Our compiler (and indeed, any OpenGL ES
shader) only uses 32-bit (and eventually vec4 16-bit) modes in normal
circumstances. Nevertheless, the other modes do exist and are easily
accessible through OpenCL; they also come up in cases like blend
shaders.
While we have had minimal support for decoding 8-bit/64-bit modes, we
did so pretending they were vec4 in each case; 16-bit registers had a
synthetically duplicated register file to separate lo/hi halves, etc.
This works for GL, but it doesn't map to what the hardware is -actually-
doing, which can cause some headscratchingly bizarre disassemblies from
OpenCL. So, we dive in the deep end and support these other modes
natively in the disassembler, using absurdly long masks/swizzles, since
the hardware is considerably more flexible than what was exposed before.
Outside of some fixed routines for blending, none of the above is
supported in the compiler yet. But it's better to have it in the ISA
definitions and disassembler than not, for future use if nothing else.

panfrost/midgard: Add shifting int modifiers
As a source modifier, shift allows shifting a value left by the bit
size, useful in conjunction with a greater register mode, for instance
to implement `upsample`. As a concrete example, the following OpenCL:
ushort hr0 = /* ... */, uint r1 = /* ... */;
uint r2 = (convert_uint(hr0) << 16) ^ b;
compiles to the following Midgard assembly:
ixor r, (hr0) << 16, b
In reverse, the ".hi" output modifier shifts the value right by the bit
size, leaving just the carry/overflow at the bottom. To implement *_hi
functions in OpenCL (for <64-bit), we do arithmetic in the 2x higher
mode with the .hi modifier. (For 64-bit, things are hairier, since there
is not an 128-bit int mode).

For floats, output modifiers determine clamping behaviour. For integers,
they determine wrapping/saturation behaviour (or shifting -- see next

While clamping behaviour for floats was clear from GL, the int behaviour
is only known From OpenCL contortion with convert_*_sat() functions.
With the underlying functions known, clean up the codebase, likely

panfrost/midgard: Note floating compares type convert
OP_TYPE_CONVERTS denotes an opcode that returns a different type than is
source (going from int-domain to float-domain or vice versa), named
after the f2i/i2f family of opcodes it covers. We care because source
mods are determined by the source type (i/f) but output modifiers are
determined by the output type (equals the source type, unless the op
type converts, in which case it's the opposite).
The upshot is that floating-point compares (feq/fne/etc) actually do
type-convert. That is, that take in floating-points and output in
integer space (a boolean), so we mark them off this way to ensure the
correct output modifiers are used.

virgl: Work around possible memory exhaustion
Since we don't normally flush before performing copy transfers, it's
possible in some scenarios to use too much memory for staging resources
and start failing. This can happen either because we exhaust the total
available memory (including system memory virtio-gpu swaps out to), or,
more commonly, because the total size of resources in a command buffer
doesn't fit in virtio-gpu video memory.
To reduce the chances of this happening, force a flush before a copy
transfer if the total size of queued staging resources exceeds a certain
limit. Since after a flush any queued staging resources will be
eventually released, this ensures both that each command buffer doesn't
require too much video memory, and that we don't end up consuming too
much memory for staging resources in total.
Fixes kernel errors reported when running texture_upload tests in glbench.

virgl: Remove incorrect resource wait condition
Now that we have copy transfers in place, we can remove the incorrect
resource wait condition. Copy transfers and other optimizations minimize
the performance impact of this removal, while providing the correct
behavior.
