Get a dummy target to allow for calculator mode while processing backticks.
This also helps break the infinite loop caused when target is null. So that we can have: $ /Volumes/data/lldb/svn/trunk/build/Debug/lldb (lldb) itob `0x123 - 0x321` 32 v 31 30 29 28 27 26 25 24 23 22 21 20 19 18 17 16 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0 [1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 0, 0, 0, 0, 0, 0, 0, 1, 0] (lldb) llvm-svn: 143260
