PATCH: Don't warn if bash is missing

Yes, when I run the tests I usually get one of two warnings: warning: Unable to find 'bash'.
or: note: Unable to find 'bash.exe'.

It depends on the setup of the buildslave.  Both the note: and warning: cause a warning on my bot.  So, I too would like to see this go away.  Thanks for the response.

I would love to see that warning go away, and this patch LGTM, but you
should wait for someone more Lit-savvy to agree before committing.

I'm not certain if this affects your bots or not, but when I test
locally, I usually wind up with:

60> note: Unable to find 'bash.exe'.
60> lit.cfg:195: note: using clang: 'E:/llvm/2013/Debug/bin/clang.EXE'
60> lit.cfg:333: note: Did not find clang-interpreter in
60> note: Unable to find 'bash.exe'.
60> lit.cfg:271: note: Did not find llvm-go in E:/llvm/2013/Debug/bin

Do you see the other notes as well?
