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.

D3D9 has a different behaviour for depth bias.
For OGL/D3D1X, the depth bias unit is the
minimal resolvable value for the depth buffer,
which depends on the format (and has different
behaviour for float depth buffers).
For D3D9, the depth bias unit is 1.0f.

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.
In theory, it might make sense to ask whether the texture validated
successfully, but just checking intel_obj->mt != NULL works for that.
