An address format representing a purely logical addressing model. In
this model, all deref chains must be complete from the dereference
operation to the variable. Cast derefs are not allowed. These
addresses will be 32-bit scalars but the format is immaterial because
you can always chase the chain. E.g. push constants in anv.

This new lowering pass implements the OpenGL ES blend pipeline in
shaders, applicable to hardware lacking full-featured blending hardware
(including Midgard/Bifrost and vc4). This pass is run on a fragment
shader, rewriting the store to a blended version, loading in the
framebuffer destination color and constant color via intrinsics as
necessary. This pass is sufficient for OpenGL ES 2.0 and is verified to
pass dEQP's blend tests. MIN/MAX modes are included and tested as well.
That said, at present it has the following limitations:
- MRT is not supported (ES3).
- sRGB support is missing (ES3).
- Extended blending is not yet ported from GLSL IR lowering (ES3.2)
- Dual-source blending is not supported. (N/A)
- Logic ops are not supported. (N/A)
v2: Fix code conventions (per Ian Romanick's feedback). Implement color
masks.
This pass should be in common nir/ space, but due to non-technical
reasons, for now it's in Panfrost space. In the future, depending if
other drivers need some of the functionality, we can move this back to
src/compiler/nir space.

This adds a forgotten decode line on Midgard and adds the field of a
blend constant on Bifrost. The Bifrost encoding is fairly weird; whereas
Midgard is just a regular 32-bit float, Bifrost uses a fancy
fixed-point-esque encoding. The decode logic here is experimentally
correct. The encode logic is a sort of "guesstimate", assuming that the
high byte is just int(f / 255.0) and then solving algebraicly for the
low byte. This might be slightly off in some cases.

For IMMEDIATE and FIFO, most games work in a pipelined manner where the
can produce frames at a rate of 1/MAX(CPU duration, GPU duration), but
the render latency is CPU duration + GPU duration.
This means that with scanout from pageflipping we need 3 frames to run
full speed:
1) CPU rendering work
2) GPU rendering work
3) scanout
Once we have a nonblocking acquire that returns a semaphore we can merge
1 and 3. Hence the ideal implementation needs only 2 images, but games
cannot tellwe currently do not have an ideal implementation and that
hence they need to allocate 3 images. So let us do it for them.
This is a tradeoff as it uses more memory than needed for non-fullscreen
and non-performance intensive applications.
Since this is pretty much a TODO that can use the context I added this as
a comment.

EGL annoyingly defines a few variants of this token:
EGL_CONTEXT_OPENGL_RESET_NOTIFICATION_STRATEGY_EXT - 0x3138
EGL_CONTEXT_OPENGL_RESET_NOTIFICATION_STRATEGY_KHR - 0x31BD
EGL_CONTEXT_OPENGL_RESET_NOTIFICATION_STRATEGY - 0x31BD
The EGL_EXT_create_context_robustness extension specifies that the EXT
token is only valid for ES contexts, not GL. The EGL_KHR_create_context
extension defines the KHR version, and says it is only allowed for GL
contexts, and specifically calls out that it's an error for ES contexts.
But EGL 1.5 includes the new suffixless token, which has the same value
as the KHR version, and specifically calls out that it's now valid to
use with both GL and ES contexts. So we should allow this.
Fixes KHR-NoContext.es32.robustness.no_reset_notification and
KHR-NoContext.es32.robustness.lose_context_on_reset on iris, which
apparently is exposing EGL 1.5.

From the Vulkan 1.1.107 spec:
Sample shading is enabled for a graphics pipeline:
- If the interface of the fragment shader entry point of the
graphics pipeline includes an input variable decorated with
SampleId or SamplePosition. In this case minSampleShadingFactor
takes the value 1.0.
- Else if the sampleShadingEnable member of the
VkPipelineMultisampleStateCreateInfo structure specified when
creating the graphics pipeline is set to VK_TRUE. In this case
minSampleShadingFactor takes the value of
VkPipelineMultisampleStateCreateInfo::minSampleShading.
Otherwise, sample shading is considered disabled.
In other words, if sampleShadingEnable is set to VK_FALSE, we should
ignore minSampleShading.

will not synchronize a subsequent map to the readback.
