This can occur during payload setup of SIMD-split send message
instructions, which can lead to the emission of header setup
instructions with a non-zero channel group and fixed SIMD width. Such
instructions could end up using undefined channel enable signals
except they don't care since they're always marked force_writemask_all.
Not known to affect correctness of any workload at this point, but it
would be trivial to back-port to stable if something comes up.

SIMD16 instructions need to have additional interferences to prevent
source / destination hazards when the source and destination registers
are off by one register.
While we already have code to handle this, it was only running for SIMD16
dispatches, however, we can have SIDM16 instructions in a SIMD8 dispatch.
An example of this are pull constant loads since commit b56fa830c6,
but there are more cases.
This fixes a number of CTS test failures found in work-in-progress
tests that were hitting this situation for 16-wide pull constants
in a SIMD8 program.

accompanied by a nir_src_bit_size() == 32 assertion to assert that we

There are some cases where the VS is the only stage enabled, it uses the
entire URB, and the URB is large enough that placing later stages after
the VS exceeds the number of bits for "URB Starting Address".
For example, on Icelake GT2, "varying-packing-simple mat2x4 array" from
Piglit is getting a starting offset of 128 for the GS/HS/DS. But the
field is only large enough to hold an offset of 127.
i965 doesn't hit any genxml assertions because it's still using the old
OUT_BATCH mechanism. 128 << GEN7_URB_STARTING_ADDRESS_SHIFT (57) == 0,
with the extra bit falling off the end. So we place the disabled stage
at the beginning of the URB (overlapping with push constants). This is
likely okay since it's a zero size region (0 entries).
It seems like the Vulkan driver might hit this assertion, however, and
the situation seems harmless. To work around this, always place
disabled stages at the start of the URB, so the last enabled stage can
fill the remaining space without overflowing the field.

Dual source blending behaviour is undefined when shader doesn't
have second color output.
"If SRC1 is included in a src/dst blend factor and
a DualSource RT Write message is not used, results
are UNDEFINED. (This reflects the same restriction in DX APIs,
where undefined results are produced if “o1” is not written
by a PS – there are no default values defined)."
Dismissing fragment in such situation leads to a hang on gen8+
if depth test in enabled.
Since blending cannot be gracefully fixed in such case and the result
is undefined - blending is simply disabled.
