880098158d nir/nir_lower_calls_to_builtins: trivially handle IA64 mangled functions 
Using __attribute__((overloadable)) when declaring nir ops with
variable-width params in clc results in their symbol names being (IA64)
mangled; this change enables the mangled names to be handled when later
lowering the calls.

1772380307 nir: Fixup 10/12 bit SW decoder YCbCr formats
Some checks are pending

Details

Details 
The highest possible values that can be represented with
16/12/10 bits are 65535/4095/1023, not 65536/4096/1024.
In order to ensure 1023 maps to 65535 in the Sx10 case
we thus need to multiply by 65535 / 1023 ~= 64.06158
instead of 64.

e78bd88a06 nir/opt_offsets: add callback to set need_nuw per intrinsic
Some checks are pending
macOS-CI / macOS-CI (dri) (push) Waiting to run
Details
macOS-CI / macOS-CI (xlib) (push) Waiting to run
Details 
Wether need_nuw is used is currently decided in two different ways:
- globally through the allow_offset_wrap option;
- per intrinsic but hard-coded in opt_offsets.

Make this more flexible by creating a callback that is called per
intrinsic. This will allow backends to decide, on a per-intrinsic basis,
whether need_nuw is needed.

Note that the main use case for ir3 is to add support for opt_offsets
for global memory accesses. Other intrinsics don't need need_nuw but
global memory accesses do.

26e32417b9 nir: Add an option to make lower_phis_to_regs_block() less clever 
Right now it tries to place reg_write instructions as far up the
predecessor chain as possible.  This is useful for a bunch of the passes
that call it since it ensures they don't get placed in dead blocks or in
single successors and things like that.  But it screws up NAK's control
flow lowering so we need the option to turn it off and make the pass
place the reg_write instructions in the most obvious place possible.

81dd60df95 nir/opt_load_skip_helpers: move divergence check earlier 
This should fix a hypothetical issue such as:
   address = load_global()
   value = load_global(address, access=uses-smem)
where divergence analysis can't prove that 'address' is uniform, but can
prove that 'value' is uniform.

We might then add both load_global to the load_worklist, but only disable
helpers for the first because the second is uniform, making 'address'
divergent for real and potentially incorrect when used with
v_readfirstlane_b32.

Some inputs is per vertex while vertex pipeline, and per primitive
when mesh pipeline. Put these inputs after other inputs to share
the same fragment shader code for two pipelines.

Instead of allocating the ralloc context, which is useless because it's
only used by the dynarray, we can free the dynarray directly.

Also share the same dynarray among all blocks instead of allocating
a new one for every block. This eliminates realloc invocations.
