[lldb-dev] Use lldb.so to create stack trace

[Zachary Turner]

Instead of linking lldb.so, which is basically an entire debugger, maybe
you could just link llvm?  I don't remember which library has the stack
trace function in llvm, but the function I believe is called
llvm::sys::printStackTrace().  This will give you a much smaller overhead
than bringing in all of lldb unnecessarily.
