Although this is not functional (and the command stream side is not
aiming for ES3 right now), this is enough to run dEQP-GLES3 shader
tests with the version override directive; this is useful, as some ES3
shader feature can occur in ES2 class shaders due to lowering.

On Midgard, float ops support standard source modifiers (abs/neg) and
destination modifiers (sat/pos/round). Integer ops do not support these,
however. To cope, we use native NIR source modifiers for floats, but
lower them away to iabs/ineg for integers, implementing those ops
simultaneously to avoid regressions.
Fixes the integer tests in
dEQP-GLES2.functional.shaders.operator.unary_operator.minus.*

Some of these are not yet fully functional due to related bugs, but this
the correct op mapping. The native ball/bany opcodes act on vec4's
unconditionally. That said, both ball and bany have the nice property
that duplicating an argument does not affect their output, so the
default "hanging swizzles" allow us to implement 2/3-component opcodes
correctly, implicitly lowering.

Our viewport code hardcoded a number of wrong assumptions, which sort of

This gets the basevertex from the draw depending on whether
it's an indexed or non-indexed draw.
We still fail a transform feedback test for vertex id, as
the vertex id actually an index id, and isn't getting translated
properly to a vertex id, suggestions on how/where to fix that welcome.

From "Alpha Coverage" section of SKL PRM Volume 7:
"If Pixel Shader outputs oMask, AlphaToCoverage is disabled in
hardware, regardless of the state setting for this feature."
From OpenGL spec 4.6, "15.2 Shader Execution":
"The built-in integer array gl_SampleMask can be used to change
the sample coverage for a fragment from within the shader."
From OpenGL spec 4.6, "17.3.1 Alpha To Coverage":
"If SAMPLE_ALPHA_TO_COVERAGE is enabled, a temporary coverage value
is generated where each bit is determined by the alpha value at the
corresponding sample location. The temporary coverage value is then
ANDed with the fragment coverage value to generate a new fragment
coverage value."
Similar wording could be found in Vulkan spec 1.1.100
"25.6. Multisample Coverage"
Thus we need to compute alpha to coverage dithering manually in shader
and replace sample mask store with the bitwise-AND of sample mask and
alpha to coverage dithering.
The following formula is used to compute final sample mask:
m = int(16.0 * clamp(src0_alpha, 0.0, 1.0))
dither_mask = 0x1111 * ((0xfea80 >> (m & ~3)) & 0xf) |
0x0808 * (m & 2) | 0x0100 * (m & 1)
sample_mask = sample_mask & dither_mask
Credits to Francisco Jerez <currojerez@riseup.net> for creating it.
It gives a number of ones proportional to the alpha for 2, 4, 8 or 16
least significant bits of the result.
GEN6 hardware does not have issue with simultaneous usage of sample mask
and alpha to coverage however due to the wrong sending order of oMask
and src0_alpha it is still affected by it.

When we destroy a context, we need to temporarily make that context
the current one for the thread.
That's because during context tear-down we make many calls to
_mesa_reference_texobj(&texObj, NULL). Note there's no context
parameter. If the texture's refcount goes to zero and we need to
delete it, we use the thread's current context. But if that context
isn't the context we're tearing down, we get into trouble when
deallocating sampler views. See patch 593e36f956 ("st/mesa:

Also, we need to release any sampler views attached to the fallback
textures.
