  Changed paths:
    M llvm/lib/ToolDrivers/llvm-lib/LibDriver.cpp

  Log Message:
  -----------
  [ms] llvm-lib gives a more useful error if no inputs and no output path are provided

Summary:
If no inputs and no output path are provided, llvm-lib should produce a useful error.

Before this, it would fail by reading from an unitialized StringRef.
