  Log Message:
  -----------
  [clang][cli] Add support for options with two flags for controlling the same field.

This enables automatically parsing and generating CC1 arguments for options where two flags control the same field, e.g. -fexperimental-new-pass-manager and -fno-experimental new pass manager.
