It is not clear from the docs exactly how pipelined STATE_BASE_ADDRESS
actually is. We know from experimentation that we need to flush the
render cache prior to emitting STATE_BASE_ADDRESS and invalidate the
texture cache afterwards. The only thing the PRM says is that, on gen8+
we're supposed to invalidate the state cache after STATE_BASE_ADDRESS
but experimentation has indicated that doing so does nothing whatsoever.
Since we don't really know, let's do just a bit more flushing in the
hopes that this won't be a problem again. In particular:
1) Do a CS stall before we emit STATE_BASE_ADDRESS since we don't
really know whether or not it's pipelined.
2) Do a data cache flush in case what runs before STATE_BASE_ADDRESS
is a compute shader.
3) Invalidate the state and constant caches after STATE_BASE_ADDRESS
because the state may be getting cached there (we don't really know).

See "glsl: Rewrite atan2 implementation to fix accuracy and handling
of zero/infinity." for the rationale, but note that the instruction
count benefit discussed there is somewhat less important for the SPIRV
implementation, because the current code already emitted no control
flow instructions -- Still this saves us one hardware instruction per
scalar component on Intel SKL hardware.
Fixes the following Vulkan CTS tests on Intel hardware:
dEQP-VK.glsl.builtin.precision.atan2.highp_compute.scalar
dEQP-VK.glsl.builtin.precision.atan2.highp_compute.vec2
dEQP-VK.glsl.builtin.precision.atan2.highp_compute.vec3
dEQP-VK.glsl.builtin.precision.atan2.highp_compute.vec4
dEQP-VK.glsl.builtin.precision.atan2.mediump_compute.vec2
dEQP-VK.glsl.builtin.precision.atan2.mediump_compute.vec4
Note that most of the test-cases above expect IEEE-compliant handling
of atan2(±∞, ±∞), which this patch doesn't explicitly handle, so
except for the last two the test-cases above weren't expected to pass
yet. The reason they do is that the i965 back-end implementation of
the NIR fmin and fmax instructions is not quite GLSL-compliant (it
complies with IEEE 754 recommendations though), because fmin/fmax of a
NaN and a non-NaN argument currently always return the non-NaN
argument, which causes atan() to flush NaN to one and return the
expected value. The front-end should probably not be relying on this
behavior for correctness though because other back-ends are likely to
behave differently -- A follow-up patch will handle the atan2(±∞, ±∞)
corner cases explicitly.
v2: Fix up argument scaling to take into account the range and
precision of exotic FP24 hardware. Flip coordinate system for
arguments along the vertical line as if they were on the left
half-plane in order to avoid division by zero which may give
unspecified results on non-GLSL 4.1-capable hardware. Sprinkle in
some more comments.

This addresses several issues of the current atan2 implementation:
- Negative zero (and negative denorms which end up getting flushed to
zero) isn't handled correctly by the current implementation. The
reason is that it does 'y >= 0' and 'x < 0' comparisons to decide
on which side of the branch cut the argument is, which causes us to
return incorrect results (off by up to 2π) for very small negative
values.
- There is a serious precision problem for x values of large enough
magnitude introduced by the floating point division operation being
implemented as a mul+rcp sequence. This can lead to the quotient
getting flushed to zero in some cases introducing an error of over
8e6 ULP in the result -- Or in the most catastrophic case will
cause us to return NaN instead of the correct value ±π/2 for y=±∞
and x very large. We can fix this easily by scaling down both
arguments when the absolute value of the denominator goes above
certain threshold. The error of this atan2 implementation remains
below 25 ULP in most of its domain except for a neighborhood of y=0
where it reaches a maximum error of about 180 ULP.
- It emits a bunch of instructions including no less than three
if-else branches per scalar component that don't seem to get
optimized out later on. This implementation uses about 13% less
instructions on Intel SKL hardware and doesn't emit any control
flow instructions.

This does point at the front-end emitting silly code that could have
been optimized out, but the current fsign implementation would emit
bogus IR if abs was set for the argument (because it would apply the
abs modifier on an unsigned integer type), and we shouldn't rely on
the upper layer's optimization passes for correctness.

This fixes rendering of full-screen quads (and other screen-filling
geometry, e.g. ioquake3 walls up-close) on gc3000. It should be a no-op
on other hardware.
- It looks like SE_CLIP registers were not set at all.
I'm amazed that rendering worked without them. Emit them to
avoid issues on gc3000.
- Define constants
ETNA_SE_SCISSOR_MARGIN_RIGHT (0x1119)
ETNA_SE_SCISSOR_MARGIN_BOTTOM (0x1111)
ETNA_SE_CLIP_MARGIN_RIGHT (0xffff)
ETNA_SE_CLIP_MARGIN_BOTTOM (0xffff)
These demarcate the margin (fixp16) between the computed sizes and the
value sent to the chip. I have set these to the numbers used by the
Vivante driver for gc2000. I am not sure whether any old hardware was
relying on the old numbers, or whether those were just a guess. But if
so, these need to be moved to the _specs structure.

Shaders using sin/cos instructions were not working on GC3000.
The reason for this turns out to be that these chips implement sin/cos
in a different way (but using the same opcodes):
- Need their input scaled by 1/pi instead of 2/pi.
- Output an x and y component, which need to be multiplied to
get the result.
- tex_amode needs to be set to 1.
Add a new bit to the compiler specs and generate these instructions

Exposing rb swapped (or other swizzled) formats for rendering would

(GPUs that need an extra resolve step anyway due to multiple pixel
pipes, such as gc2000, might also do this swap in the resolve operation.
But this would be tricky to keep track of)
