Tested versions

Reproducible in: master (f50d7fa), 4.5.stable, 4.4.stable, 4.3.stable (these versions crashes with output), 4.2.2.stable (crashes silently)

System information

Godot v4.5.stable - Windows 10.0.26100 - DX12 (Forward+) - dedicated NVIDIA GeForce RTX 4070 Laptop GPU (NVIDIA; 32.0.15.7260) - 13th Gen Intel(R) Core(TM) i9-13980HX (32 Threads)

Issue description

When rendering with DX12 and with --generate-spirv-debug-info enabled, the editor crashes immediately upon startup with the following output:

SPIR-V parsing FAILED:
    In file godot-mesa/src/compiler/spirv/spirv_to_nir.c:6180
    Unhandled opcode: SpvOpPhi (245)

    12008 bytes into the SPIR-V binary

Steps to reproduce

1. Open a project (a minimal 3d project would be OK) and set rendering_device/driver.windows to d3d12 in project settings.
2. Close the project and reopen it with --generate-spirv-debug-info then the editor crashes immediately.

Minimal reproduction project (MRP)

Any project that uses DX12 as the windows rendering driver.
