clang-cl: Various changes to /Zc: handling. * /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

[clang-cl] Alias /Zc:alignedNew[-] to -f[no-]aligned-allocation Implements PR40180. clang-cl has one minor behavior difference with cl with this change. Clang allows the user to enable the C++17 feature of aligned allocation without enabling all of C++17, but MSVC will not call the aligned allocation overloads unless -std:c++17 is passed. While our behavior is technically incompatible, it would require making driver mode specific changes to match MSVC precisely, and clang's behavior is useful because it allows people to experiment with new C++17 features individually. Therefore, I plan to leave it as is. llvm-svn: 351249
