This patch implements Value::dump related code so the pretty printing
will work.

The problem for the patch is that it doesn't work with 'template types'
like all the STL components. For exmaple:
clang-repl> #include <memory>
clang-repl> auto p = std::make_shared<int>(42);
clang-repl> p

JIT session error: Symbols not found: [ _Z17PrintValueRuntimeIiENSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEEEPSt10shared_ptrIT_E ]
(shared_ptr<int> &) ERROR: Failed to materialize symbols: { (main, { _Z23__InterpreterCallPrint1B5cxx11v }) }
