This adds a unit test for the copy_bitwise function in dwarf2loc.c. With the old (broken) version of copy_bitwise this test would generate the following failure message: (gdb) maintenance selftest Self test failed: copy_bitwise 11000000 != 10000000 (7+2 -> 0) gdb/ChangeLog: 2016-11-24 Andreas Arnez <arnez@linux.vnet.ibm.com> Pedro Alves <palves@redhat.com> * dwarf2loc.c (bits_to_str, check_copy_bitwise) (copy_bitwise_tests): New functions. (_initialize_dwarf2loc): Register the new function copy_bitwise_tests as a unit test. * selftest.c (run_self_tests): Improve the failure message's wording and formatting.
