SPIR-V: Initialize undefined variables with 0 (#3526)
* 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 Co-authored-by: gdkchan <gab.dark.100@gmail.com> Co-authored-by: gdkchan <gab.dark.100@gmail.com>
