Log:
Reapply: [llvm-size] Tidy up error messages (PR42970)
Clean up some formatting inconsistencies in the error messages and correctly exit with non-zero in all error cases.
Originally submitted as r374771 and then reverted as r374780, this patch fixes the libObject test case in Object/macho-invalid.test.
