emit_urb_writes() contains code to emit an EOT write with no actual
data when there are no output varyings. This makes sense for the VS
and TES stages, where it's called once at the end of the program.
However, in the geometry shader stage, emit_urb_writes() is called once
for every EmitVertex(). We explicitly emit a URB write with EOT set at
the end of the shader, separately from this path. So we'd better not
terminate the thread. This could get us into trouble for shaders which
do EmitVertex() with no varyings followed by SSBO/image/atomic writes.
It also caused us to emit multiple sends with EOT set, which apparently
confuses the register allocator into not using g112-g127 for all but
the first one. This caused EU validation failures in OglGSCloth
shaders in shader-db. (The actual application was fine, but shader-db
thinks there are no outputs because it doesn't understand transform
feedback.)

The only part of an ir_texture which can be an array is the
offsets array in textureGatherOffsets() calls. We don't want
to lower those, because they're required to remain constants.
Fixes textureGatherOffsets with Gallium drivers such as llvmpipe,
which commit ef78df8d3b regressed.

The intent was to continue down the indirect chain, not to call ourselves
with unchanged input arguments. Found by code inspection, and comparison
to copy_prop_alu_src().
We haven't hit this because callers of NIR's copy prop are doing so in
SSA, before indirect variable dereferences have been lowered to registers.

It defaults to true so default behavior doesn't change but it allows you to
do NIR_VALIDATE=false if you don't want validation. Disabling validation
can substantially speed up shader compiles so you frequently want to turn
it off if compiler invariants aren't in question.

Empirical tests show that the polygon offset
behaviour is entirely determined by the content of
the PA_SU_POLY_OFFSET states, and not by the depth buffer
format bound.
PA_SU_POLY_OFFSET seems to directly set the parameters of
the polygon offset formula, and setting 0 for
PA_SU_POLY_OFFSET_DB_FMT_CNTL (ie setting the unorm depth
bias behaviour with a scale of 2^0 = 1.0f) gives the unscaled
behaviour.

On MRF platforms, we need to set base_mrf to the first MRF value we'd
like to use for the message. On send-from-GRF platforms, we set it to
-1 to indicate that the operation doesn't use MRFs.
As MRF platforms are becoming increasingly a thing of the past, we've
forgotten to bother with this. It makes more sense to set it to -1 by
default, so we don't have to think about it for new code.
I searched the code for every instance of 'mlen =' in brw_fs*cpp, and
it appears that all MRF-based messages correctly program a base_mrf.
Forgetting to set base_mrf = -1 can confuse the register allocator,
causing it to think we have a large fake-MRF region. This ends up
moving the send-with-EOT registers earlier, sometimes even out of
the g112-g127 range, which is illegal. For example, this fixes
illegal sends in Piglit's arb_gpu_shader_fp64-layout-std430-fp64-shader,
which had SSBO messages with mlen > 0 but base_mrf == 0.

The old return type of GLuint was wonky - it should have been bool.
But nothing actually uses the return value anyway, so we can just drop
that and make it a void function.
