r192848 - Remove an old, seemingly out of date, comment.

[Alp Toker]

For the record, looks like the tests were added in r140673 to
consolidate predefined macros but the script that generated them was
never checked in.

Perhaps Chandler could share his generate_arch_predefine_tests.sh --
seems a worthy effort someone could pick up.

ChangeLog from r140673:

    Begin fixing Clang's predefined macros for various architectures. This
    is *very* much a WIP that I'll be refining over the next several
    commits, but I need to get this checkpoint in place for sanity.
   
    This also adds a much more comprehensive test for architecture macros,
    which is roughly generated by inspecting the behavior of a trunk build
    of GCC. It still requires some massaging, but eventually I'll even check
    in the script that generates these so that others can use it to append
    more tests for more architectures, etc.
   
    Next up is a bunch of simplification of the Targets.cpp code, followed
    by a lot more test cases once we can reject invalid architectures.
