TGSI, byte code and logging output

With sb enabled some shaders apparently trigger an endless loops in the sb
optimizer.=20

The attached TGSI and log of a shader triggering this behaviour comes from =
the
Unreal Editor version 4.17.1,=20=20

The log was created with=20

  #define PSC_DEBUG 1=20

in src/gallium/drivers/r600/sb_sched.cpp

The problem is probably related to the "FIXME rework this loop" o=
n line 1808 in
the same file, and I also have the impression that it has something to do w=
ith
MULADD when the sources are a mix of CONST and IMM.

I'd try to fix it myself, but right now I don't really have a clue how to
approach this bug.

Shader triggering the endless loop

I think the last log was not correct, i.e. it was not the right shader. This
new log shows different error messages. The the endless loop is happening in
"post_scheduler".=20

I've run the code with R600_DEBUG=3Dnocw,sbdump in addition to the PSC_DUMP=
.=20
I've also tried R600_DEBUG=3Dsbsafemath, but to no avail.

Snip of the log:=20
