this is much easier to read and is going to greatly simplify the eventual
multidraw implementation which will be dropped in
also it allows moving conditionals outside of loops to very slightly improve
drawoverhead performance (with multidraw)

The current policy is to always favor accumulators if possible, however,
this is not always optimal.
Particularly, accumulators play a crucial role in enabling QPU instruction
merges, since these are limited to both the ADD and the ALU instructions
addressing at most 2 physical registers. For 2-src instructions, this means
that to be able to merge we need them to address at least 2 accumulators.
While favoring accumulators does help the case for instruction merges in
general, it is risky to assign accumulators to variables that have
long life spans. Doing so will make the accumulator unavailable for
any other instructions during that life span, and since we only have a few
accumulators, we can quickly run out and losing our capacity to merge
instructions for large parts of the qpu program.
On the other hand, we also want to avoid the extreme case were we keep
allocating physical registers to the point we run out, even if we have
accumulators available, since accumulators have additional restrictions
and may not be suitable for everything.
This change continues the policy of favoring accumulators, but it only
does so if the life span of the temps is short, to ensure that we can
recycle accumulators often across instructions and avoid running out
for sections of the QPU code, unless we are already running out of
physical registers.

Blending in SP_BLEND_CNTL is not a binary flag but the same
mask as in RB_BLEND_CNTL. It is a per-mrt enable bit for blending.
Example SP_BLEND_CNTL produced by blob on a630 and different MRT
blendings:
SP_BLEND_CNTL: { UNK8 | 0x6 }
SP_BLEND_CNTL: { ENABLED | UNK8 | 0xe }

We can do stuff like this:
vec1 32 ssa_207 = fsum3 ssa_209.xxx
In this case, we'd end up not swizzling in get_alu_src, and reading
components out-of-bounds, which LLVM isn't very happy about, and thus
takes punitive actions, in the form of a segfault.
We don't want that, and we already know from the opcode what the
component counts should be here.

This pass was originally developed for Panfrost, where it passes the
relevant dEQP tests. Upstreaming so it can be extended and then shared
with:
* Asahi, for blending
* Zink, for logic ops
* Lavapipe, for advanced blending
Note that using this with MRT in a fragment shader (as non-panfrost
drivers will) has not yet been tested. Logic ops with integer
framebuffers are probably todo. It's been enough for Panfrost, will
suffice for ES2 on Asahi, and provides an upstream base for kusma's work
on advanced blending, so overall the merge is a net benefit.

as host-side formatsto be combined with the internal formats
RGB8/SRGB8 and RGBA8/SRGB8_ALPHA8 respectively.
This extension is of interest to support a subset of OpenGL in
virtualized environments where the host only supports GLES.
