clang-cl: add the /c, /W0 and /W1 options This adds a few more clang-cl options. It also exposes two core clang options to the clang-cl mode: we need to be able to claim --driver_mode so it doesn't show up as unused in cl mode, and we need -### for tests.

clang-cl: ignore compile-only options in link-only invocations. Previously we would warn about unused arguments such as /MD when linking. Clang already has logic to ignore compile-only options, e.g. for -D and -U. This patch extends that to include clang-cl's compile-only options too. Also, some clang-cl options should always be ignored. Doing this earlier means they get ignored both for compilation and link-only invocations. llvm-svn: 190825

Fix test/Driver/cl-options.c test The test builds an object file to be able to get into linking mode with a valid obj file on the command-line. Using clang-cl for this, which targets win32, caused problems on some buildbots, so just use regular clang. llvm-svn: 190829

clang-cl: parse (but don't support) the /o flag Apparently folks run into this (PR17097). The flag is not supported by MSVC either, but we should parse it so we don't get confused when it occurs. This changes the clang-cl output for "clang-cl /c /o foo.obj" from: clang-cl.exe: error: no such file or directory: '/o' clang-cl.exe: error: no such file or directory: 'foo.obj' to: clang-cl.exe: warning: argument unused during compilation: '/o bajs.obj' llvm-svn: 190323

clang-cl: ignore /RTC options (PR17129) I don't think Clang intends to implement this functionality. ASan should be used instead. Since /RTC is often passed by default from MSBuild, ignore the option to avoid bloating the output. llvm-svn: 190202
