When raw profiles stores (optionally filename prefixed) linkage names while
global identifier uses the (filename prefixed) mangled name, the particular use
case would be broken. Is it possible to convert objective-c mangled name to
linkage name (needed by linker) in the post-processing of raw profiles? And do
you think it make sense for the use case of D156569?
Say raw profiles still stores `[filepath;]mangled-name`, and `llvm-profdata`
takes it to generate the linkage name that `-symbol-ordering-file` wants.
