Frontend: Handle empty input on stdin. - PR3854. I think it makes more sense to change MemoryBuffer::getSTDIN (return 0 should indicate error, not empty), but it is documented to return 0 for empty inputs, and some other code appears to rely on this. llvm-svn: 67448 2009-03-21 17:55:43 +00:00			`// RUN: clang -E - < /dev/null &> %t`
