[PATCH] D32796: [Driver] Add a "-mmacos_version_min" option that's an alias for "-mmacosx_version_min"

[Alex Lorenz via Phabricator via cfe-commits]

arphaman created this revision.

The option `-mmacosx_version_min` will still be the canonical option for now, but in the future we will switch over to `-mmacos_version_min` and make `-mmacosx_version_min` an alias instead.
