Lionel added a neat debugging tool. Let's make it work with the new-style
hashing approach too, since nir_printf_fmt is a lot more convenient than needing
to define a dedicated CL function to access printf (although that works too).
We remove the old non-hashed path, because it has no more functional users --
hashing is a hard requirement with vtn_bindgen2, which Intel has now switched
to.

this is now handled in vtn_bindgen2 for vtn path code. this does drop support
from printf from GRL but that seems appropriate at this point.

Now using the same model as the compute shader.
As a result we temporarily disable the use of the Inline register for
providing push constants on Task & Mesh shaders. Since that register
is also available on the compute shader we'll try to find a way to use
the same mechanism for all 3 shaders in another MR and bring back that
optimization.

For Xe3+ the registers are tightly packed to make better use of GRF
space, so add a statistic to keep track of how many registers were used.
For previous versions this is not useful since the code is spreading
the registers among the whole space.

Some compiles don't initialize the upper 32bits of the union that has
u64 addr and u32 handle.
Similar to previous patches but doing that for code in intel/misc.

The handle and addr fields of drm_xe_sync is defined as the union:
union {
__u32 handle;
__u64 addr;
};
When initialized on the stack on certain implementations, setting
.handle will leave the upper bits of .addr/the overall union
uninitialized causing exec calls to fail with:
[drm:xe_sync_entry_parse [xe]] Ioctl argument check failed at drivers/gpu/drm/xe/xe_sync.c:136: upper_32_bits(sync_in.addr)
Somewhat awkward but init .addr first to 0 and then set the handle after
the struct init.

There were 4 fields:
- key: now will be passed explicitly, so we can reuse the existing
more general fs_visitor constructor;
- input_vue_map: used only by the client code brw_compile_gs, so
create it separatedly as a local variable;
- two unsigned parameters: just put them inside a nested struct in the
shader.

After optimization happen, if the sources are still in one or two
contigous spans for some reason (e.g. some data read from memory
now being written), it is beneficial to just use regular SEND
and avoid having to set the ARF scalar instruction.

Add an optimization pass to turn regular SENDs into SEND_GATHERs.
This allows the payload to be "broken" into smaller pieces that
can be further optimized, which _may_ result in
- less register pressure (no need to contiguous space), and
- less instructions (no need to MOV to such space).
For debugging, the INTEL_DEBUG=no-send-gather option skips this
optimization, and reporting how many opportunities were missed.

Starting in Xe3, there's a variant of SEND that take the
register numbers from the ARF scalar register, and don't
require them to be contiguous. The new opcode added here
represents that kind of SEND.
To make the original sources still reachable, we keep them
around during the IR, just ignoring them at generator time.
This allow software scoreboard to properly reason the
dependencies without trying to decode the contents of ARF
scalar register being used.

only Gfx9+. This option must be true to build Crocus or Hasvk.
This allows skipping re-building ELK when developing for newer platforms
