            Bug ID: 20040
           Summary: clang crash while trying to print-before-all:
                    Assertion failed: ((*I)->getFunction() && "Expecting
                    non-null Function")

Clang built from r210980 crashes when I try to print debug IR for any C or IR
file. I'm running on OS X 10.9.3:

$ cat test.ll
define i32 @main() #0 {
entry:
  ret i32 0
}

-----------------------------------------------------------------

$ ./clang -mllvm -print-before-all test.ll
