The pipeline register creation algorithm is only valid for SSA indices;
NIR registers and such cannot be pipelined without more complex
analysis. However, there are the ocassional class of "liars" -- indices
that claim to be SSA but are not. This occurs in the blend shader
prologue, for example. Detect this and just bail quietly for now.
Eventually we need to rewrite the blend shader prologue to occur in NIR
anyway (which would mitigate the issue), but that's more involved and
depends on a better understanding of pixel formats in blend shaders (for
non-RGBA8888/UNORM cases).
Fixes some blend shader regressions.

This piece of code was cargo-culted from the ir3 standalone compiler and
made sense when we were a standalone compiler ourselves. Unfortunately,
for the online compiler, mesa/st *already handles this for us* and if we
duplicate it here, we're duplicating it *incorrectly*. So just delete

If by flush time the client hasn't submitted a clear, add jobs for
reloading the framebuffer contents as the first draw in the frame.
This is required by programs such as Weston which don't do clears and
rely on the previous contents of the framebuffer being there.
Reloading the whole framebuffer on every frame without regards to what
is needed or what is going to be covered is very inefficient, but future
work will introduce support for damage regions and partial updates so we
know what needs to be actually reloaded.
Fixes quite a few tests in dEQP-EGL.functional.buffer_age.*.
[Alyssa: The context is that tilers do an implicit glClear() on every
frame, whether you asked them to or not. If you want a clear, this is
very efficient. But if you don't, you have to explicitly blit the
backbuffer back into tile memory, accomplished by a dummy texturing
draw. This patch generates that draw via u_blitter, although we could do
a bit better ourselves by eliding the vertex job. This fixes "black
rectangles in Weston/sway" as well as "video not displaying when UI
visible in mpv"]

The mesa/st flips the viewport, so we respect that rather than
trying to flip the framebuffer itself and ignoring the viewport and
using a messy heuristic.
However, this brings an underlying disagreement about the interpretation
of winding order to light. The blob uses a different strategy than Mesa
for handling viewport Y flipping, so the meanings of the winding order
bit are flipped for it. To keep things clean on our end, we rename to
explicitly use Gallium (rather than flipped OpenGL) conventions.
Fixes upside-down Xwayland/egl windows.

Instead, we add a new helper which stomps one nir_shader and replaces it

In a fragment shader, r0 is written out with a special branch sequence.
r0 is not a real register here, but essentially a pipeline register --
as such, it needs to be written out in full and on time, with hanging
dependencies in the bundle. Otherwise, we break up the bundle, which
costs an extra ALU cycle and adds a move.
When the scheduler ran last thing, we could do this analysis within the
scheduler. Now that RA can run after scheduling, that's no longer valid,
so we remove the analysis and always break it up (at a performance
penalty). Future work can add a post-RA/post-schedule pass to merge
writeout blocks if possible. It's a bit of a low-priority next to fixing
conformance regressions, of course.

Memory corruption meant that #0 was instead random noise. For some ops,

scheduling due to extra constants in random places). But for others,
where a 1-op is emulated by a 2-op with an implicit 0 second argument,
that broke things.
