[llvm-objcopy] Add additional testing for various cases
This patch adds a number of tests to test various cases not covered by existing tests. All of them work correctly, with no need to change llvm-objcopy itself, although some do indicate possible areas for improvement. Reviewed by: MaskRay Differential Revision: https://reviews.llvm.org/D61727 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@360422 91177308-0d34-0410-b5e6-96231b3b80d8
