[Reland] Use llvm symbolizer for stack script.
llvm symbolizer is a more efficient symbolizer than addr2line, objdump,
etc.
In this cl, I 1)created a wrapper instance to interact with
llvm symbolizer, 2)made the stack script to use llvm symbolizer instance,
and then 3)added llvm symbolizer into isolated inputs.
