[PATCH] D35477: [ELF] - Print options aliases in --help

[George Rimar via Phabricator via llvm-commits]

grimar created this revision.
Herald added a subscriber: emaste.

This is PR 30422,
previously LLD did not render option aliases in --help.

Also help output contained sduplicates for few options, for example:

  --build-id=<value> Generate build ID note
  --build-id Generate build ID note

Patch fixes that all. Example of output:
