* SPIR-V: Initialize undefined variables with a value
Changes undefined values on spir-v shaders (caused by phi nodes) to be initialized instead of truly undefined.
Fixes an issue with NVIDIA gpus seemingly not liking when a variable is _potentially_ undefined. Not sure about the details at the moment.
Fixes:
- Tilt shift blur effect in Link's Awakening (bottom of the screen)
- Potentially block flickering on newer NVIDIA gpus in Splatoon 2? Needs testing.
Testing is welcome.
* Update Ryujinx.Graphics.Shader/CodeGen/Spirv/CodeGenContext.cs
