New Revision: 144029

URL: http://llvm.org/viewvc/llvm-project?rev=144029&view=rev
Log:
[analyzer] Make sure scan-build catches all clang failures.

scan-build ignores clang failures in some cases, which might lead to
silent failure suppression. For example, if clang command line
argument is wrong. (Addresses radar://10406598)
