  Changed paths:
    M lld/MachO/Driver.cpp
    M lld/MachO/Options.td
    M lld/test/MachO/icf-options.s

  Log Message:
  -----------
  [lld/mac] Don't warn on both --icf=all and -no_deduplicate

Instead, just make the later flag win, like usual.
Implement this by making -no_deduplicate an actual alias for --icf=none
at the Options.td level.
