Add an lldb wrapper script that implements gdb-compatible commands on top
of lldb. This will be the new default method for executing the tests in
this repository on Darwin.
There is also a related patch for llvm/utils/test_debuginfo.pl coming.

I also relaxed some of the checks to work with both gdb's and lldb's
output.
