This is the instruction that the hardware actually supports. Do the rename, use
the more specific accurate model in the IR, and rework the Valhall texturing

Valhall does not have Bifrost's 4-source MKVEC.v4i8. Instead, it has a (somewhat
limtied) 3-source MKVEC.v2i8. The full MKVEC.v4i8 may be lowered to a pair of
MKVEC.v2i8 instructions.
For good code quality on both Bifrost and Valhall, we need to model both
instructions in their full generality.

This avoids needless variation from Bifrost. While at it, fix the opcode
definition: there are no abs/neg/swizzle modifiers on the signed integer source,
and there's no clamp. However, there are round and infinity modes, like on

This pass is super easy to unit test, so we have no excuse not to test
thoroughly. va_mark_last only inserts annotations in a shader without any
annotations, so our test cases are simply annotated shaders. The CASE macro just
has to compare the case against the case with the annotations stripped and added
back with va_mark_last.
In retrospect, I should have used that technique for the flow control insertion
tests too.

On Valhall, register reads may be marked as "last" [1]. Setting the last flag
promises the hardware that the value of the register is no longer required. This
may enable hardware optimizations. In particular, it may permit the hardware to
avoid register file writes if a write to the marked register is still in the
forwarding buffer. This may improve power efficiency.
In principle, this is trivial: run liveness analysis and mark killed sources,
like we would in an SSA-based register allocator. In practice, there are a few
wrinkles to avoid hazards around staging registers and 64-bit register pairs,
requiring some additional data flow analysis and fix ups. However, nothing here
is particularly "hard", and all the ideas are already in use for the Bifrost
scheduler and the Bifrost/Valhall scoreboard analyses.
[1] In Mesa's compiler, this is called discard for historical reasons.

This helps "contain the crazy" and avoids special casing BLEND in compiler

Post-RA liveness relies on the caller updating the live variable with the
results of bi_postra_liveness_ins. It is not automatic, as with regular
liveness. This means ignoring the result of bi_postra_liveness_ins is surely an
error. Mark it as MUST_CHECK to catch that error at compile time.

For some unknown reason, waiting for general slots (at least for memory stores)
doesn't work properly on a BARRIER instruction. We need to wait for all general
slots right before issuing the BARRIER in addition to the general wait on the
BARRIER itself. I don't know if this is a hardware bug or some hideous
gate-saving quirk, but I observe the Mali-G78 DDK using the same workaround,
which implies this really is necessary.
Fixes rare flakes in:
dEQP-GLES31.functional.compute.shared_var.work_group_size.float_128_1_1
Note that the flakes from that test are extremely timing dependent. Without this
change, that test is racy but we almost always win the race. Reproducing the
issue reliably requires high system load (e.g. running the CTS in the
background) and simultaneously running that test a large number of times.
Minimal shader-db impact. In particular, no cycle count regressions.
