clang-cl: print diagnostics as "error(clang): foo" in /fallback mode
This solves two problems:
1) MSBuild will not flag the build as unsuccessful just because we print
an error in the output, since "error(clang):" doesn't seem to match
the regex it's using.
2) It becomes more clear that the diagnostic is coming from clang as
supposed to cl.exe.
