In order to allow inlining of previously out-of-line functions without an ABI break libc++ provides legacy definitions in the dylib that old programs can continue to use. Unfortunatly Windows link.exe detects this hack and diagnoses the duplicate definitions. This patch disable the duplicate definitions on Windows by adding an ABI option which disables all "legacy out-of-line symbols" llvm-svn: 292190
