panfrost/midgard: Handle pure int formats

I'm not sure I'm totally comfortable with this, but conceptually neither
float nor pure-int formats require any format conversion, except size
conversion. Going from a shaderable format (fp32 or i16, for instance)
into a blendable format (fp16) is a separate question, one we can defer
momentarily while we're not interested in actually blending.

As an aside, I'd be fascinated by an integer-based blending
implementation.

Oh, dear. No turning back now.

type-converting moves; substantially more efficient operation is
possible by copypropping the type conversion modifier, but this
optimization is not implemented here.

Size converting modifiers on Midgard allow an instruction to write to a
destination 1/2 the size, or to read from a source 1/2 the size. If we
need an extreme conversion (32-bit to 8-bit, for instance), multiple

nir/loop_analyze: Refactor detection of limit vars

This commit reworks both get_induction_and_limit_vars() and
try_find_trip_count_vars_in_iand to return true on success and not
modify their output parameters on failure.  This makes their callers

nir: Add some helpers for chasing SSA values properly

There are various cases in which we want to chase SSA values through ALU
ops ranging from hand-written optimizations to back-end translation
code.  In all these cases, it can be very tricky to do properly because
of swizzles.  This set of helpers lets you easily work with a single
component of an SSA def and chase through ALU ops safely.

nir/loop_analyze: Bail if we encounter swizzles

None of the current code knows what to do with swizzles.  Take the safe

nir/loop_analyze: Fix phi-of-identical-alu detection

One issue was that the original version didn't check that swizzles
matched when comparing ALU instructions so it could end up matching
very different instructions.  Using the nir_instrs_equal function from
nir_instr_set.c which we use for CSE should be much more reliable.
Another was that the loop assumes it will only run two iterations which
may not be true.  If there's something which guarantees that this case
only happens for phis after ifs, it wasn't documented.

virgl: improve virgl_transfer_queue_is_queued

Search only the pending list and return immediately on the first
hit.

When the transfer queue was introduced, the function was used to
deal with

  write transfer -> draw -> write transfer

sequence.  It was used to tell if the second transfer intersects
with the first transfer. If yes, the transfer queue avoided
reordering the second transfer to before the draw (by flushing) in
case the draw uses the transferred data.

With the recent changes to the transfer code, the function is used
to deal with

  write transfer -> readback transfer

We want to avoid reordering the readback transfer to before the
first transfer (also by flushing).

In the old code, we needed to track the compeleted transfers as well
to avoid reordering.  But in the new code, a readback transfer is
guaranteed to see the data from the completed transfers (in other
words, it cannot be reoderered to before the already completed
transfers).  We don't need to search the COMPLETED_LIST.
