Testing negative iterations count makes no sense, and can cause issues
when the unsigned type is used.
Testing 0 iterations is already covered with
will_break_on_first_iteration, so it can be skipped too.

@decl_reg intrinsics must be in the first block so it's convenient to be
able to create an insertion point after all @decl_regs when the first

Once decl_reg is handled, src[0].ssa->divergent will be properly set, so

shader-db can run to completion on HSW, IVB, and SNB now. No other

In the wise words of Mike Blumenkrantz, "I hate gl_PointSize and so can you".
The mesa/st lowering won't mesh well with vertex shader epilogues, and it falls
over in various circumstances. I am too tired to go against the grain, so let's
just pretend to be a normal gallium driver and trust in the rasterizer CSO,
lowering point size internally. This properly handles transform feedback without
any hacks, both GL and GLES behaviours, etc.

The NIR intrinsics now take and return a barrier whenever one is
modified instead of modifying in-place. In NAK, we give the internal
instructions the same treatment and convert everything to use barrier
SSA values and RegRefs. In nak_from_nir, we move all barriers to/from
GPRs. We'll clean up the massive pile of OpBMov later.

asahi will pass in 16bits, works fine if we convert before clamping. note we
don't try to be clever and make a smaller immediate because it would require
extra logic for negatives to make sure we don't have garbage in upper bits
(nir_validate checks that). do the simple, obviously correct thing.
