Simon Zünd 5bddc0e142 Implement top-level await for REPL mode 
Design doc: bit.ly/v8-repl-mode

This CL allows the usage of 'await' without wrapping code in an async
function when using REPL mode in global evaluate. REPL mode evaluate
is changed to *always* return a Promise. The resolve value of the
promise is the completion value of the REPL script.

The implementation is based on two existing mechanisms:
  - Similar to async functions, the content of a REPL script is
    enclosed in a synthetic 'try' block. Any thrown error
    is used to reject the Promise of the REPL script.

  - The content of the synthetic 'try' block is also re-written the
    same way a normal script is. This is, artificial assignments to
    a ".result" variable are inserted to simulate a completion
    value. The difference for REPL scripts is, that ".result" is
    used to resolve the Promise of the REPL script.

  - ".result" is not returned directly but wrapped in an object
    literal: "{ .repl_result: .result}". This is done to prevent
    resolved promises from being chained and resolved prematurely:

    > Promse.resolve(42);

    should evaluate to a promise, not 42.
