Although it's kind-of similar to "(rptN)" in the shader ISA, I called it
"xmov" to make it clear that it's completely orthogonal to "(rep)",
although you certainly can use both modifiers on the same instruction.

With triangle fans when "first vertex convention" is active the
provoking vertex is actually the second vertex so that the different
triangle can have different colors with flat shading. Take this into
account when re-ordering the vertex indices (as proposed by Erik)

This adds a config-option to u_primconvert that translates primitive
restart values to the max-values for the index size. This allows us to
support arbitrary primitive-restart indices on hardware that only
supports fixed restart-indices.

This struct allows us to pass the configuration as a struct, which can
more easily be extended to take more arguemnts as long as we're careful
about zero-initialization.
We keep the old create-function, but implement it as a wrapper on top so
we don't have to update all existing call-sites right now.

These blocks are all the same logic, but with a few details changed.
Let's add a parameterized version and add calls to that instead.

Expanding the primitive-type has two undesirable effects:
1. It breaks primitive-restart. This is possible to fix by explicitly
handling primitive-restart in more conversion routines. But
u_indices_gen.py is kind of a mess, so it's not trivial as-is.
2. It changes the reported gl_VertexID.
While it might be possible to work around this in each driver, it seems
better to avoid this when we can.

Some drivers need to know which streams are used by a geometry
shader. Adding a mask of active streams makes the use of
UsesStreams superfluous as it's the equivalent of:
ActiveStreamMask != (1 << 0)

The round-to-nearest-even implementation found in lower_2f() is incorrect
for any value having a significand that is not directly representable
and whose non-representable part lies between 1 and half the minimum
representable value. In this case, the significand is rounded up instead
of being rounded down.

For some unfathomable reason, three out of these four tests often time
out when running within CI. On the assumption that there is some
parallelisation badness happening rather than the non-UNIX tests
entering infinite loops, try just marking them as serial-only.
This should have a negligible impact on runtime since they are quick to
execute.
