[PATCH] D106316: [clang][darwin] Add support for the -mtargetos= option to the driver

[Steven Wu via Phabricator via cfe-commits]

steven_wu added a comment.

Looks good in general. Just one corner case that we need to decide with direction we go, following command builds arm64-ios and x86_64-ios-simulator:
`clang -arch arm64 -arch x86_64 -c -o test.o test.c -mios-version-min=14`
Should we document and deprecate that behavior?
