source dir for LLVM to be specified explicitly. This removes the dependency on the llvm-config script. If the option is not given, then the scripts use llvm-config which should be both built and in the PATH. This arrangement provides a useful default for most developers but also allows the nightly tester to execute countloc.sh before llvm-config is built and without altering the PATH. llvm-svn: 29663
