[PATCH] clang-cl: print errors as "err" when in /fallback mode

[Hans Wennborg]

  > Would you still want the Clang errors to show up in the output? "warning: clang error: " would accomplish that, but I'm not sure if that's an improvement.

  MSBuild treats "warning: clang error: foo" as an error. Fun times :)

  Spelling errors as "err" still makes them show up in the output window, and clicking on them to go to the source location works too. They don't show up in the error list view, but I think that's OK.
