aco: do not apply OMOD/CLAMP for pseudo scalar trans instrs
...
macOS-CI / macOS-CI (dri) (push) Waiting to run
macOS-CI / macOS-CI (xlib) (push) Waiting to run
This optimization seems broken because eg. v_s_log_f32 uses SGPRs
for both the source and destination but applying OMOD seems to require
VGPRs.
This fixes a GPU hang when launching Enshrouded on GFX1201.
No fossils db changes on GFX1201.

aco/tests: Add tests for precolored operands in different regs
...
The first test verifies that, if possible, we don't emit unnecessary
renames/copies for temporaries where it's possible for them to stay
in their current register (if an operand is precolored to the register
the temporary is currently residing in).
The second test verifies that we correctly choose a non-clobbered
operand even if there is one fixed to the temporary's current register.
To minimize copies, we'll want to have the live copy of
%tmp0 in v[2] there, because v[0-1] gets overwritten.
The third test verifies that we add a copy to another free register and
rename if all possible precolored operands are clobbered.

aco/sched_ilp: reorder VINTRP
...
VINTRP(gfx6-gfx10.3) is mostly just VALU, but we treated it like memory
instructions as an afterthought. This had issues as VINTRP was never reordered
with itself, or other memory instructions. Reordering VINTRP in clauses
increases ILP. We don't really need collect_clause_dependencies for VINTRP
either, because they ususally have the same dependencies already. That means
we can still form VINTRP clauses by selecting preferably VINTRP after a
previous one.

aco/assembler: chain branches instead of emitting long jumps
...
As regular branch instructions cannot jump further than
32768 dwords, previously we used long jumps as fallback
solution. The disadvantage of that is that an extra SGPR
pair must be provided in order to temporarily store the PC.
This patch changes that to chained branch instructions by
inserting an artificial extra block into the code to be
targeted by the original branch. This block contains a
single branch instruction jumping to the original target.
Before the block, if necessary, we insert a <branch 1>
instruction for the existing code in order to jump over
the newly inserted block.
Only a few RT shaders are affected.
