Darwin, Objective-C: Support -fconstant-cfstrings [PR108743].
This support the -fconstant-cfstrings option as used by clang (and
expect by some build scripts) as an alias to the target-specific
-mconstant-cfstrings.
The documentation is also updated to reflect that the 'f' option is
only available on Darwin, and to add the 'm' option to the Darwin
section of the invocation text.
