These are jobs for which we may want to enable double-buffering,
which affects tile state allocation. Since the idea is that we
want to decide about double buffering late, we also want to
postpone allocation of the tile state until we are about to
emit the RCL for the job.

If we enable double-buffer we are reducing the tile size, and thus,
we'll need more tiles and a larger tile state allocation, so we'll
need to call to this helper.

MSAA is not compatible with double-buffer mode. Also, jobs that emit
tile loads or that don't have any stores can't take advantage
of double-buffer mode.

With this change, the idiv lowering will produce mul_high instructions,
so we need to instruct the compiler to lower those with the ALU lowering
right after the idiv lowering by adding the lower_mul_high option (we
only need to add this to V3D, since V3DV already had it set). This will
cause injection of uadd_carry instructions, for which we have backend
implementations that produce better code for us than the NIR lowering.

Right now if we use the option SHADERDB, NORAST is added
automatically. There's no comment justifying it, neither a lot of info
on the commits that added that. But I guess that the purpose is that
SHADERDB option is assumed to be used only to gather shader-db stats,
so setting setting NORAST would allow to get those dumps faster.
But adding debug options automatically can be confusing, as we could
get a behaviour that we were not expecting. At least I needed to check
why using SHADERDB was getting a black screen. And if we want to get
this behaviour, we can easily add manually the NORAST.
Finally, v3dv doesn't support NORAST right now (and we don't have
immediate plans to implement it), so it is somewhat inconsistent to
get different behaviour from the same debug option from the two
drivers.

For some reason the Vulkan spec required that these features must be
supported even though they only affect features that are optional
in Vulkan 1.2 and that we don't support, so enabling them doesn't
have any practical implications for us.

We only want to cleant BCL barrier flags if we consume a BCL barrier.
For example, if the client records a barrier for an index buffer
it should apply to the next draw call that uses an index buffer
which may not be the current draw call but one coming after it.

Two advantages:
* When using NIR_DEBUG=nir_print_xx, will print outcome only if
there is a change
* We can use NIR_PASS(_, ...) instead of NIR_PASS_V, that has
slightly more validation checks.
This includes:
* v3d_nir_lower_image_load_store
* v3d_nir_lower_io
* v3d_nir_lower_line_smooth
* v3d_nir_lower_load_store_bitsize
* v3d_nir_lower_robust_buffer_access
* v3d_nir_lower_scratch
* v3d_nir_lower_txf_ms
As we are here we also simplify some of them by using the

The trigger for this commit was when we found that we were not calling
nir_metadata_preserve when lowering the layout code. But then I found
that it would be better to just update the code to use
nir_shader_instructions_pass, so we can avoid to manually:
* Initialize the nir_builder
* Call nir_foreach functions (we pass the callback)
* Call nir_metadata_preserve functions (that as mentioned we were not calling)
We also get a nice cleanup of several functions by reducing the number
of parameters (we pass a state struct).

This feature allows shaders to use pointers to buffers which may
not be bound via descriptor sets. Access to these buffers is done
via global intrinsics.
Because the buffers are not accessed through descriptor sets, any
live buffer flagged with VK_BUFFER_USAGE_SHADER_DEVICE_ADDRESS_BIT_KHR
can be accessed by any shader using global intrinsics, so the driver
needs to make sure all these buffers are mapped by the kernel when
it submits the job for execution.
We handle this by tracking if any draw call or compute dispatch in
a job uses a pipeline that has any such shaders. If so, the job is
flagged as using buffer device address and the kernel submission
for that job will add all live BOs bound to buffers flagged with the
buffer device address usage flag.
