Includes: - Shift to use of spirv-header extinst.nonsemantic.shader grammar.json - Remove extinst.nonsemantic.vulkan.debuginfo.100.grammar.json - Enable all optimizations for Shader.DebugInfo Also fixes scalar replacement to only insert DebugValue after all OpVariables. This is not necessary for OpenCL.DebugInfo, but it is for Shader.DebugInfo. Likewise, fixes Private-to-Local to insert DebugDeclare after all OpVariables. Also fixes inlining to handle FunctionDefinition which can show up after first block if early return processing happens. Co-authored-by: baldurk <baldurk@baldurk.org>
