[llvm-size] Fix hang waiting for input on invalid short commandline option

When an invalid shot command line option was used (e.g. -v) llvm-size
would hang waiting on input from stdin. This change fixes this issue by
bringing llvm-size in line with other llvm tools and exiting early when
this error is output.
