There were several different ways of handling the option to f18 to find predefined modules: - test_errors.sh was created by cmake substituting FLANG_INTRINSIC_MODULES_DIR into test_errors.sh.in - some tests used the flang script which has the option built it - some tests used %f18_with_includes which was replaced by the path to f18 plus the -I option - some included -I../../include/flang in their run command To make this more consistent, change %f18 to include the -intrinsic-module-directory option and use it everywhere, including to replace %flang and %f18_with_includes. This requires changing all of the invocations of the test scripts to put %f18 at the end so that it can expand to more than one argument. This eliminates the need to generate test_errors.sh which means we don't need flang/test/Semantics/CMakeLists.txt or the %B substitution. That makes the test_errors.sh command like the others, replacing %B/test/Semantics/test_errors.sh with %S/test_errors.sh. Also remove the OPTIONS: functionality as custom options can be included in the RUN: command. And remove -I/../../include/flang as that is now always included.
