Emission of `mustprogress` attribute previously occurred only within `EmitFunctionBody`, after generating the function body. Other routines for function body creation may lack the attribute, potentially leading to suboptimal optimizations later in the pipeline. Attribute emission is now anticipated prior to generating the function body. Fixes: https://github.com/llvm/llvm-project/issues/69833.
