ralloc_steals it back to NULL but it's more consistent and probably

We used to print invalid data when the last field was being clamped to
32bits due to Dword Length of the whole instruction. Here is an
example where the decoder read part of the next instruction instead of
stopping at the 32bit limit:
0x000ce0b4: 0x10000002: MI_STORE_DATA_IMM

Groups containing fields smaller than a DWord were not being decoded
correctly. For example:
<group count="32" start="32" size="4">
<field name="Vertex Element Enables" start="0" end="3" type="uint"/>
</group>
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.
Caught by Matt Turner while working on 3DSTATE_VF_COMPONENT_PACKING,
with a patch to convert it to use an array of bitfields (the example
above).

Fixes intermittent GPU hangs on Broxton with an Intel internal
test case.
There are plenty of similar fragment shaders in piglit that do
not use any varyings and any uniforms. According to the
documentation special timing is needed between pipeline stages.
Apparently we just don't hit that with piglit. Even with the
failing test case one doesn't always get the hang.
Moreover, according to the error states the hang happens
significantly later than the execution of the problematic shader.
There are multiple render cycles (primitive submissions) in between.
I've also seen error states where the ACTHD points outside the
batch. Almost as if the hardware writes somewhere that gets used
later on. That would also explain why piglit doesn't suffer from
this - most tests kick off one render cycle and any corruption
is left unseen.
v2 (Ken): Instead of enabling push constants, enable one of the
inputs (PSIZ).
v3 (Ken, Jason): Use LAYER instead making vulkan emit_3dstate_sbe()
happy.

In order to implement the ballot intrinsic, we do a MOV from flag
register to some GRF. If that GRF is used in a SEL, cmod propagation
helpfully changes it into a MOV from the flag register with a cmod.
This is perfectly valid but when lower_simd_width comes along, it simply
splits into two instructions which both have conditional modifiers.
This is a problem since we're reading the flag register. This commit
makes us check whether or not flags_written() overlaps with the flag
values that we are reading via the instruction source and, if we have
any interference, will force us to emit a copy of the source.
