f0ba7d897d made debug_assert()/assert()
unsafe for expressions, but only now that u_atomic.h started to rely on
them for Windows that this became an issue.
This fixes non-debug builds with MSVC.

We support MOCS on both gen8 and gen9, so the message seems meaningless. Remove
it to avoid confusion.
Trivial.

The odds of having this patch make a difference on Gen8+ are probably very low.

Because all topologies are reduced to basic primitives (i.e. no strips, fans)
and the vertices involved are all copied, there's no need for any elaborate
decisions where to insert the prim id. The logic employed was correct for
first provoking vertex, but didn't account at all for the last provoking
vertex case. And since we now will get the right constant value even if the
primitive type is later changed (for unfilled etc.) this is no longer
required to pass certain tests (which were checking for prim_id == some
const interpolated value so passing because both were wrong in the end).
This is a bit overkill (3x4 values assigned in total even though it's really
one scalar per prim...) but the code is now much easier and I don't need to
add more cases for last provoking vertex.
This fixes piglit primitive-id-no-gs-strip test.

Previously the first provoking vertex convention would only be used if
flatshading were enabled. No matter how I look at it that cannot be possibly
correct. Maybe the code getting used was somewhat simpler that way at a time
where there weren't constant interpolated attributes, only flatshading...
(Note that all other places including the decomposition macros already do
the same.)

This stage only worked for traditional old-school flatshading, it did ignore
constant interpolated values and only handled colors, the code probably
predates using of constant interpolated values in gallium. So fix this - the
clip stage apparently did this a long time ago already.
Unfortunately this also means the stage needs to be invoked when flatshading
isn't enabled but some other prim changing stages are - for instance with
fill mode line each of the 3 lines in a tri should get the same attribute
value from the leading vertex in the original tri if interpolation is constant,
which did not happen before
Due to that, the stage is now run in more cases, even unnecessary ones. Could
in theory skip it completely if there aren't any constant interpolated
attributes (and rast->flatshade isn't set), but not sure it's worth bothering,
as it looks kinda complicated getting this information in advance.
No piglit change (doesn't really cover this directly).

Just like we do for tris (det shouldn't matter at this point, however
can have flags for things like line stipple reset).
No piglit change, it would fail line stippling tests if the flatshade
stage were run, which will happen with the next commit.

The previous language was a bit misleading, since it sounded like
w was interpolated then the reciprocal calculated which isn't what
should be happening.

With everything in place, we can now use the scalar backend compiler for
vertex shaders on BDW+. We make scalar vertex shaders the default on
BDW+ but add a new vec4vs debug option to force the vec4 backend.
No piglit regressions.
Performance impact is minimal, I see a ~1.5 improvement on the T-Rex
GLBenchmark case, but in general it's in the noise. Some of our
internal synthetic, vs bounded benchmarks show great improvement, 20%-40%
in some cases, but real-world cases are mostly unaffected.
