patch 8.0.0448: some macros are in lower case

commit https://github.com/vim/vim/commit/b5aedf3e228d35821591da9ae8501b61cf2e264c
Author: Bram Moolenaar <Bram@vim.org>
Date:   Sun Mar 12 18:23:53 2017 +0100

    patch 8.0.0448: some macros are in lower case

    Problem:    Some macros are in lower case, which can be confusing.
    Solution:   Make a few lower case macros upper case.
