Move can take in a vector and write a scalar, depending on the swizzle. We need
to handle this case. Split out mov and pack_32_2x16 so we can specify correct
behaviour for both. Also drop unused 1-bit boolean stuff which obscured the fix.

"Revisiting Out-of-SSA Translation for Correctness, Code Quality, and
Efficiency" discusses "value-based interference": two variables interfere if and
only if there exists a point in the program where they are both live *with
different values*. In particular, the source and destination of a move do not
interfere a priori, because they have the same value at that point in the
program. (If a later instruction overwrites one, the required interference will
be added there).
We can use this idea to avoid some extra interferences, avoiding a regression in
moves from split/collect.

If we don't lower phis to scalar, when we go out of SSA, we can get vector
nir_registers. In particular, we can get code like:
r0 = vec2 r0.y, r0.x
This code looks like a move, but is in fact a swap. The trivial lowering of vec2
would not work -- the following fails to swap correctly:
r0.x = r0.y
r0.y = r0.x
Currently, we generate temporaries to handle these cases. It's easy to move the
complexity to NIR, though, and we'll want to scalarize phis for SSA-based RA
anyway.

Some older drivers don't support GLSL versions with the concept of flat
varyings and also don't support integers. Here we add a new setting to

This setting helps us avoid marking varyings as flat and therefore
potentially having them changed to ints via varying packing.

now it can also be D16_UNORM. The assert isn't protecting us from
anything we weren't already doing before so we can just loosen it a bit.

Each shader stage has its own "early preamble" flag.
Early preamble is likely an optimization to hide some of latency
when loading UBOs into consts in the preamble.
Early preamble has the following limitations:
- Only shared, a1, and consts regs could be used
(accessing other regs would result in GPU fault);
- No cat5/cat6, only stc/ldc variants are working;
- Values writen to shared regs are not accessible by the rest
of the shader;
- Instructions before shps are also considered to be a part of
early preamble.
Note, for all shaders from d3d11 games blob produced preambles
compatible with early preamble mode.

This reverts commit 68ef895674.
When trying out transcode_astc=true with BPTC on Asphalt 9, we observed
very poor image quality - to the point that basic UI icons were blocky,
and buttons with a black border had smeared pixels on the edges. Using
DXT5 had no such issues.
I originally suspected there was a bug in the BPTC encoder, but I now
believe the issue is deeper than that. The commit that introduced the
encoder, 17cde55c53, says:
"The compressor is written from scratch and takes a very simple
approach. It always uses a single mode of the BPTC format (4 for
unorm and 3 for half-floats) and picks the two endpoints by dividing
the texels into those which have more or less than the average
luminance of the block and then calculating an average color of the
texels within each division.
It's probably not really sensible to try to use BPTC compression at
runtime because for example with the Nvidia offline compression tool
it can take in the order of an hour to compress a full-screen image.
With that in mind I don't think it's worth having a proper compressor
in Mesa and this approach gives reasonable results for a usage that
is basically a corner case."
In other words, the reason our BPTC compressor was so fast is that it
only implements one of the modes and does a low quality approximation.
This honestly should probably be improved somewhat, but the original
use case was for online-compression, the uncommon but mandatory OpenGL
feature where you can supply uncompressed data and trust the driver to
compress it for you (at unknown and uncontrolled quality and speed).
Unfortunately, the compressor as it stands is simply not usable for
transcoding ASTC data where we want to preserve the underlying image
quality as much as possible.
