This reverts commit 52c7df1643. The pass,
while clearly useful for some shaders, has at least three bugs that I
was able to find fairly quickly:
1. It doesn't work for type-converting MOVs because f > 0 is not the
same as f2i(f) > 0
2. CSEL is a 3src instruction and only supports one source type; it
doesn't take this into account and tries to create instructions
which do a F compare and a D select. This is especially nasty to
debug because you don't see that in the dumped assembly because we
don't properly assert that types are the same in codegen.
3. While you can handle 2, in theory, by reinterpreting types, you
can't do that in the presence of source modifiers. This pass
doesn't even attempt to detect that.
Those are just the ones I found with the one almost trival shader I was
debugging. There very likely may be more and. Best thing to do for now
is just shut it off until someone has the time to figure out how to do
this properly and write tests to ensure it's correct.

Do not link libgallium_nine with libgalliumvl_stub if it's already
linked with libgalliumvl. Linking with stub leads to "duplicate

bit and will make it easier to later add 16-bit versions as well.

Specifically when we are in non-uniform control flow, as we would need
to set the condition for the last instruction. If (for example) a
image atomic load stores directly their value on a NIR register,
last_inst would be a nop, and would fail when set the condition.

Rather than open-coding checks on gpu_id in the compiler, let's track
quirks applying to whatever we're compiling for, to allow us to manage
the complexity of many heterogenous GPUs in the compiler.
It was discovered that a workaround used on T720 is also required on
T820 (and presumably T830), so let's fix this. This will also decrease
friction as we continue improving T720 support.

This will allow us to continue searching the current path for
relative shader includes.
From the ARB_shading_language_include spec:
"If it is quoted with double quotes in a previously included
string, then the first search point will be the tree location
where the previously included string had been found."
