[JIT] pass more exception info through the JIT interpreter
If TORCH_SHOW_CPP_STACKTRACES=1, then dump e.what() into the RuntimeError, which should make it easier to debug exceptions that happen within interpreted sections.
Test:

^ use this to repro the interpreter issue: `TORCH_SHOW_CPP_STACKTRACES=1 ./bin/test_jit --gtest_filter="EliminateDeadCodeTest.interpreterfailure"` and the stack trace is shown.
