Instead of emitting a single one at the top, and making reference to it,
emit the virtual instruction as needed and let CSE do its job.
Since load_subgroup_invocation now can appear not at the start of the
shader, use UNDEF in all cases to ensure that the liveness of the
destination doesn't extend to the first partial write done here (it was
being used only for SIMD > 8 before).
Note this option was considered in the past
6132992cdb but at the time dismissed. The
difference now is that the lowering of the virtual instruction happens
earlier than the scheduling.
The motivation for this change is to allow passes other than the NIR
conversion to use this value. The alternative of storing a `brw_reg` in
the shader (instead of NIR state) gets complicated by passes like
compact_vgrfs, that move VGRFs around (and update the instructions).
This and maybe other passes would have to care about the brw_reg.

For some purposes (e.g. advanced blending) we need a non-zero alpha
value returned from reads. This is only guaranteed on Bifrost if
we explicitly request RGB1 component ordering. The default is to use
RGBA component ordering, which for R5G6B5 causes 0 to be read for
alpha.
A complication is that the Mali fixed function hardware requires
four components (which implies RGBA rather than RGB1). If fixed
function blending is in use, we modify the pixel format back to
RGBA when building the blend descriptor.

We have to swizzle the border color in order to offset the
automatic swizzling introduced to compensate for limited
component order support in AFBC/AFRC. However, the border color
format is only available if the `TEXTURE_BORDER_COLOR_QUIRK` is
enabled, so set that for v10 (it was already set for v7).
While testing, we uncovered another issue: valhall introduces a
swizzle for depth+stencil formats that isn't present for bifrost, and
also isn't needed (or wanted) for the border color. So ignore the
border color swizzle for depth+stencil on valhall (on bifrost the
swizzle is a no-op anyway).
Fixes: 87aad0a5e4 ("panfrost: encode component order as an inverted swizzle (v10)")
