The implementation for dumping shader line numbers was broken for anv as of:
1de9f367e8 anv: remove unused gfx/compute pipeline code
Now the implementation is moved to the shader heap upload and mimics the
current implementation in iris.

Like accumulators and ARF address registers, the virtual address
registers are not tracked in a way the defs analysis can know
about. This could actually be fixed, but that is future work.

brw_reg::nr encodes both which ARF it is and which instance of that
ARF. In other words, nr for acc0 and acc2 have some bits that say
BRW_ARF_ACCUMULATOR and some bits that say 0 vs 2. The previous test
would only detect acc0.

This can occur if NULL or an accumulator is an explicit destination.
update_for_reads still needs to process the sources.
v2: Pass a brw_reg to ::mark_invalid, and do the VGRF check in that one
place.

Applications often miss emitting barriers between a shader
initializing data & another shader writing data in the same location
afterward. This is very common for UAVs (see vkd3d-proton).
Vkd3d-proton does a pretty good job as inserting missing barriers
between UAV clears & writes. But some applications also have similar
issues with custom shaders. Here we introduce an analysis pass that
recognize shaders doing clear/initialization. We'll use that
information in the following commit to insert barriers after those
shaders.
Since Gfx12.5 our HW has become a lot more sensitive to those issues
due to the introduction of an L1 untyped data cache that is not
coherent across the shader units. On Gfx20+, typed data is also L1
cacheable exposing even more issues.

This doesn't have a functional impact, but when this command is run:

It causes the gen125_rt.xml file to be processed in the expected

Coverity notes that we break out of the loop walking the analysis_ranges
early if n_push_ranges >= max_push_buffers, so it notes that
n_push_ranges could already be 3 or 4 (depending on whether we're doing
mesh), and that then if we need the padding we insert another, which
would write past the end of the array.
I don't think this is actually possible in practice, but we can add an
assert to both keep coverity happy and detect that this has actually
happened.
