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.

gcc/ChangeLog:
* config/darwin.opt: Add fconstant-cfstrings alias to
mconstant-cfstrings.
* doc/invoke.texi: Amend invocation descriptions to reflect
that the fconstant-cfstrings is a target-option alias and to
add the missing mconstant-cfstrings option description to the
Darwin section.
(cherry picked from commit cdd4b3c0f0f428678c24de74b1f626628450799c)
