This changes the output of `llvm-readelf -n` from: ``` Displaying notes found at file offset 0x<...> with length 0x<...>: ``` to: ``` Displaying notes found in: .note.foo ``` And similarly, adds a `Name:` field to the `llvm-readobj -n` output for notes. This change not only increases GNU compatibility, it also makes it much easier to read notes. Note that we still fall back to printing the file offset/length in cases where we don't have a section name, such as when printing notes in program headers or printing notes in a partially stripped file (GNU readelf does the same). Fixes llvm.org/PR41339. Reviewed By: MaskRay Differential Revision: https://reviews.llvm.org/D75647
