My latest divination spell has uncovered a pattern in the aether.
Although the swizzle is unaligned, its format is otherwise standard.
Document this, removing the old incorrect understanding of the swizzle
(which coincided on common special swizzles only).

The blob uses COMPUTE jobs for some internal purposes. These are
essentially free but panfrost doesn't use them, so it messes up the
numbering. Just filter them out.

This is a hack since we do have native gradient stuff, but for the
moment I'm more interested in conformance and the lowered code is good
enough. Fixes

I'm honestly unsure what this is for, but it's needed on MFBD systems
for unknown reasons, at least when MRT is actually in use and then
sometimes without MRT (it fixes a blend shader issue on T760?)

Epilogues are special fixed-function blocks, so they need special
handling for liveness analysis to work completely. This in turns fixes
RA issues for many shaders using MRT.

The flow is considerably more complicated. Instead of one writeout loop
like usual, we have a separate write loop for each render target. This
requires some scheduling shenanigans to get right.

not necessary and it does break things. Somehow this gives the RA more

We would like no_spill decisions to be class-specific -- spilling from
special register to a work register doesn't preclude also spilling that

This allows us to spill two 128-bit values in the same bundle, since we
have two registers we can spill with. This improves the
register allocation flexibility in programs with heavy spilling, though
unfortunately it isn't sufficient (theoretically, 3.5 128-bit values can
be spilled from 3 vector units and 2 scalar units).
