This fixes "unused-local-typedef" warnings in 9324e6a7a5. This adds an option `--remove-note=[name/]type` to selectively delete notes in ELF files, where `type` is the numeric value of the note type and `name` is the name of the originator. The name can be omitted, in which case all notes of the specified type will be removed. For now, only `SHT_NOTE` sections that are not associated with segments are handled. The implementation can be extended later as needed. RFC: https://discourse.llvm.org/t/rfc-llvm-objcopy-feature-for-editing-notes/83491
