panfrost: Reload framebuffer contents if there's no clear

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

sources are ever used outside of the immediate bundle in which they are

More interestingly, this slims down midgard_bundle to be essentially an
array of _pointers_ to midgard_instructions (plus some bundling
metadata), rather than the instructions and packing themselves. The

it doesn't affect the schedule) midgard_instrucitons can now be modified
_after_ scheduling while having changes updated in the final binary.

On a more philosophical level, this removes an IR. Previously, the IR
before scheduling (MIR) was separate from the IR after scheduling
(post-schedule MIR), requiring a separate set of utilities to traverse,

panfrost/midgard: Extend RA to non-vec4 sources

This represents a major break with the former RA design. We now use
conflicting register classes to represent the subdivision of Midgard's
128-bit registers into varying sizes and arrangement. We determine class
based on the number of components in the instructions' masks. To support
this, we include a number of helpers in the RA to allow composing
swizzles and masks, such that MIR written implicitly assuming .xyzw
sources can be transformed to use actual (non-aligned) sources.

The net result is a marked decrease in register pressure on
non-vec4-exclusive shaders. We could still be doing much better. Not
implemented yet are:

   - Register spilling
   - Per-component liveness

panfrost/midgard: Set masks on ld_vary

These masks distinguish scalar/vec2/vec3 loads from the default vec4,
which helps with assembly readability (since it's immediately obvious
how many components are _actually_ affected, rather than doing
mysterious things to an unknown number of unused components). Later in
the series, this will enable smarter register allocation, as the unused
components will not be interpreted abnormally.

intel/fs: Add an UNDEF instruction to avoid excess live ranges

With 8 and 16-bit types and anything where we have to use non-trivial
strides registersto deal with restrictions, we end up with things that
look like partial writes even though we don't care about any values in
the register except those written by that instruction.  This is
particularly important when dealing with loops because liveness sees
is_partial_write and the fact that an old version from a previous loop
iteration may be valid at that point and extends all purely partially
written values to the entire loop.

This commit adds a new UNDEF instruction which does nothing (the
generator doesn't emit anything) but which does a fake write to the
register.  This informs liveness that we don't care about any values
before that point so it won't consider those registers to be falsely
live.  We can safely emit UNDEF instructions for all SSA values that
come in from NIR and nearly all temporaries generated by various stages
of the compiler.  In particular, we need to insert UNDEF instructions
when we handle region restrictions because the newly allocated registers
are almost guaranteed to be partially written.

No shader-db changes.
