Commit e99e7aa4 began passing start > 0 to indexed draw calls rather
than keeping start at 0 and manually advancing ib->ptr. This should
work fine, however, there have been instances of software fallbacks
not handling things right.
vbo_sw_primitive_restart had a bug where it was ignoring "start" and
always calling find_sub_primitives with start = 0 and end = ib->count.
This meant that when start > 0, it was analyzing the wrong part of the
index buffer when finding subprimitives.
In theory, each _mesa_prim can have a different "start" value. But
the code only calls find_sub_primitives once, because it wants to
map, analyze, and unmap the index buffer before calling ctx->Draw,
as some drivers don't support drawing with the index buffer mapped.
To handle this, we break vbo_sw_primitive_restart calls into sections
where "start" matches across all the primitives, similar to how I
handled the issue in tnl in commit bd6120f562.
In the common case, start matches and we handle it in one pass anyway.
Fixes Piglit's primitive-restart VBO_COMBINED_VERTEX_AND_INDEX test
and KHR-GL33.pipeline_statistics_query_tests_ARB.functional_primitives_vertices_submitted_and_clipping_input_output_primitives
on Intel Ivybridge and older (which don't do arbitrary cut indices).

Fixes: 1784dd22a3 ('broadcom/compiler: pipeline smooth ldvary sequences')
Reviewed-by: Alejandro Piñeiro <apinheiro@igalia.com>

When we were only able to pipeline smooth varyings, if we had to disable
ldvary pipelining in the middle of a sequence it would stay disabled for
the rest of the program, to prevent us from prioritizing scheduling of
ldvary instructions that we would not be able to pipeline effectively.
Now that we can pipeline all ldvary sequences we can change this.
This change re-enables ldvary pipelining upon finding the next
ldvary in the program in the hopes that we can continue pipelining
succesfully. To do this, we track the number of ldvary instructions we
emitted so far and compare that to the number of inputs in the fragment
shader we are scheduling. This also allows us to simplify our ldvary
tracking at nir to vir time, since that is all now handled in the QPU
scheduler.
