doc: freshen up Mac OSX build instructions (#9618)
This PR brings the Mac OSX build instructions up to date slightly. (They
currently refer to facts "...as of November 2014...")

- Remove specific OS version number from the title as it is out of date
with respect to filename.

- Nonetheless don't change filename for the sake of not breaking
incoming links.

- Update C++ language version to C++14, which I believe is what is
currently required, based on other platform documentation.

- Bump versions of C++ compilers that seem to be current. I expect the
exact values of these version numbers aren't crucial but maybe good for
the reader calibrating a vague sense of whether their compiler is in the
right ballpark.

- Add `lld` to the homebrew clang instructions, because homebrew changed
the way they package llvm tools, spinning the linker off into its own
package.
