Fix and restore the macro-multiline.c test This test didn't work as intended and was ultimately disabled some years ago in r169458. Indeed it's not clear if the '\n' was ever passed through to the driver correctly given that lit would insert '&& {' at the newline. Test rewritten to use printf/xargs to insert '\n' in a more reliable manner and to use FileCheck for verification. llvm-svn: 206703 2014-04-20 05:40:58 +08:00			`// RUN: printf -- "-DX=A\nTHIS_SHOULD_NOT_EXIST_IN_THE_OUTPUT" \| xargs -0 %clang -E %s \| FileCheck -strict-whitespace %s`
