As per the comment this was meant to tidy things up after varying
linking but varying linking has been moved into a nir based linker
so this extra call is no longer needed.
This optimisation pass is still called in the regular glsl ir
optimisation loop.

We have to use a 3D draw to make it possible (so it goes through the
binner's visibility calcs), but hopefully the increased overhead for apps
with non-skippable rendering balances against skipping in others.
The real motivation is to get draw-time state out of tile load setup.

When !fb->binning but fb->binning_possible, we can just set the VSC
per-tile visibility reg to all visible in the "whoops, we'd rather not bin

Use an internal geometry shader to handle input primitives. Do full
accurate culling and clipping in the shader and output hit result and
min/max depth to a SSBO for final being written to select buffer.
With multiple result slots in SSBO we can left multiple draws on the
fly and wait them done when buffer is full or exit GL_SELECT mode.
This provides quicker selection response compared to software based
solution. Tested on Discovery Studio 2020: some complex model needs
1~2s selection response time originally, now it's almost selected
immidiately.

When glthread not enabled, CurrentClientDispatch and CurrentServerDispatch
should be same. This does not cause problems before because OutsideBeginEnd
and BeginEnd have same BeginEnd entries, so when
CurrentServerDispatch==OutsideBeginEnd
CurrentClientDispatch==BeginEnd
will call into same BeginEnd _mesa_* functions.
But we'll add another dispatch table to replace BeginEnd when HW GL_SELECT
mode, so this needs to be fixed. Otherwise some function like _mesa_Rectf
which always call with CurrentServerDispatch will go into wrong entries.

Like other optimizations, breaking this pass may not affect functional
correctness. It's also dead simple to unit test the pass, so we have no excuse
not to. Add unit tests for the functionality we currently support, since we just
extended it and want to make sure everything still works.
This includes tests for use of modifiers to get more small constants. There are
lots of subtle gotchas there, so let's add lots of unit tests to make sure we
got it right.

Some blitter operations, like clear, doesn't require to save all the
states.
This is particular important because, besides saving time, the blitter
operation restores the state required for the operation, and if we saved
more states than those, these ones won't be restored and will be leak.
So this also fixes some leaks when running CTS tests.

CSEL executes on the conversion unit (CVT), while MUX executes on the special
function unit (SFU). Throughput on CVT is 4x higher than SFU, so this is
(almost) always an optimization.
The "real" MUX is still used for unusual cases, like 8-bit and bitselect.
Note that it's easier for us to use MUX everywhere for the IR. This is an easy
fixup to get better codegen on Valhall without touching the core Bifrost code.
shader-db is a bit of a toss up: register pressure and instruction count are
hurt in some cases due to restrictions on FAU access. In particular, a shader
that muxes between two uniforms needs an extra move due to extra constant
(zero). However, in terms of throughput this is still a win: 2 CVT instructions
(MOV + CSEL) have 2x throughput to 1 SFU instruction (MUX). The MOV has
opportunities for CSE, but that can hurt pressure in turn. Overall, cycles are
helped substantially.
