If the shader cache is enabled, after linking the program, we
serialize the program to nir. This will be saved out by the glsl

Later, if the same program is found in the cache, we can use the nir

i965: Fix ARB_indirect_parameters logic.

This patch modifies the ARB_indirect_parameters logic in
brw_draw_prims, so that our implementation isn't affected if
another application attempts to use predicates. Previously we
were using a predicate with a DELTAS_EQUAL comparison operation
and relying on the MI_PREDICATE_DATA register being 0. Our code
to initialize MI_PREDICATE_DATA to 0 was incorrect, so we were
accidentally using whatever value was written there. Because the
kernel does not initialize the MI_PREDICATE_DATA register on
hardware context creation, we might inherit the value from whatever
context was last running on the GPU (likely another process).
The Haswell command parser also does not currently allow us to write
the MI_PREDICATE_DATA register. Rather than fixing this and requiring
an updated kernel, we switch to a different approach which uses a
SRCS_EQUAL predicate that makes no assumptions about the states of any
of the predicate registers.

gen_field_iterator_next would properly walk over each element of the
array, incrementing group_iter, and calling iter_group_offset_bits()
to advance to the proper DWord.  However, the code to print the actual
values only considered iter->field->start/end, which are 0 and 3 in the
above example.  So it would always fetch bits 3:0 of the current DWord
when printing values, instead of advancing to each element of the array,
printing bits 0-3, 4-7, 8-11, and so on.

To fix this, we add new iter->start/end tracking, which properly
advances for each instance of a group's field.
