Documentation: Clarify a few subtleties
* Clarify accepted values of <LANG> suffix in CMAKE_COMPILER_IS_GNU<LANG>.
* Clarify fact that target property GENERATOR_FILE_NAME usually cannot be
used at configure time.
* Clarify that enable_language() can only be used in global scope of
top-level project using language.
* State that enable_language(... OPTIONAL) currently doesn't work.
* Document regular expression operator precedence.
