This is necessary to prevent a regression from a future commit,
in order to allow us to map output locations differently.

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)")

Allow llvmpipe to run on Android without any drm device present.
Previously llvmpipe would only run with kms_swrast, still requiring
a drm device driver to be present for the display.

This new trait is way more generic and shareable. It does mean a bit of
gymnastics with traits to keep from retyping the whole compiler but the
result is something we can potentially share with other compilers.

This adds explicit lifetimes to any function which looks at a NIR
object, fishes a pointer out of it, and returns a reference. The theory
of operation for these NIR wrappers is that everything holds an implicit
shared reference to the whole shader and so this is safe to do as long
as no one ever has a mut reference to anything. However, since these
methods are turning pointers into references, it's a lot more obvious
what's going on if we have explicit lifetimes.
