12256136e0 compiler: Rename shader_prim to mesa_prim and replace all usage of pipe_prim_type with mesa_prim
This is a prepare step to remove depends on p_defines.h in src/util/*

This is done by:
replace pipe_prim_type with mesa_prim
replace shader_prim with mesa_prim
replace PIPE_PRIM_MAX  with MESA_PRIM_COUNT
replace SHADER_PRIM_  with MESA_PRIM_
replace PIPE_PRIM_ with MESA_PRIM_

This patch only replace code only

2d3fbb44f4 nir: Add preserve_mediump as a shader compiler option
The DXIL backend would like to distinguish between casts to 16-bit
that must cast, vs those that may. If a shader only ever produces
16-bit types from mediump casts and ALU ops on those values, then
the resulting shader can be annotated with DXIL's min-precision
qualifier, basically telling the driver to use 16-bit precision if
it's faster for them. If it uses concrete 16-bit casts, or loads/
stores to externally-visible memory, then it must use the "native"
16-bit flag, which is not supported on all hardware.

a28540a430 meson: add feature option for use of system Clang headers at runtime
Enabling or disabling the "microsoft-clc" option previously changed

In addition, the option to avoid the use of system Clang headers at
runtime is useful outside the scope of Windows.

Separating the two concepts by making this a neutral feature option

3df3c38a65 nir/opt_gcm: allow resource_intel to be moved anywhere
The resouce_intel intrinsic doesn't not result in an actual
instruction, it's just a wrapper around another value, usually a
load_const.

Allowing this intrinsic to be moved anywhere means it's going to be
closer to the value it wraps, enabling opt_gcm to move a load_ubo
using this resource_intel.

54dfc08b89 nir: add a new intrinsic to describe resources accessed on intel
Intel HW has multiple ways to access resources like UBO/SSBO/images :

   - binding tables : a small ~240 heap of surfaces

   - bindless surfaces : a 64Mb heap of surfaces up to Gfx12+, 4Gb on Gfx12.5+

   - surfaces : a 4Gb heap on Gfx12.5+ (mostly unused at the moment,
     only available through the LSC)

For samplers, we have 2 options since Gfx11+ :

   - samplers indexed from the Dynamic State Heap (4Gb)

   - samplers indexed from the Bindless Sampler Heap (4Gb)

Additionally our whole push constant promotion mechanism is based
around binding table indices. This is problematic if you want to also
promote to push constants things that would be accessed through the
bindless heap.

To solve this issue, we introduce a new intrinsic that will cary a
block index that is not based off the binding table index nor the
bindless table offset.

We will also use this intrinsic to identify whether the buffer/surface
index in load_ubo/load_ssbo/store_ssbo/etc... is relative to the
binding table or the bindless heap.

5d238c0c2c nir_lower_returns: Optimize phis before beginning the pass
This adds a little extra work, since now dominance is computed and
blocks that don't just have then-return or else-return are looked at.
However it means that nir_lower_returns can now keep phis up to date
