llvm/test/LTO/no-undefined-puts-when-implemented.ll
Kevin Enderby 138222e56f Change the default input for llvm-nm to be a.out instead of standard input
to match llvm-size and other UNIX systems for their nm(1).

Tweak test cases that used llvm-nm with standard input to add a "-" to
indicate that and add a test case to check the default of a.out for llvm-nm.
