* /Zc:trigraphs and /Zc:trigraphs- are now honored * /Zc:strictStrings is now honored * /Zc:auto is now honored/ignored (clang does the Right Thing for this already) Also add a dedicated test for the various /Zc: flags. clang-cl doesn't always agree with cl.exe on the default values for /Zc flags. For example, I think clang always behaves as if /Zc:inline is passed, and warns if the user explicitly passes /Zc:inline- Fixes PR21974. llvm-svn: 224791
