Benedikt Meurer 379331b7a4 [debugger] Don't attach source positions to implicit returns. 
Previously we'd attach source positions to implicit returns that are
generated when leaving an async function with a promise rejection. This
was due to the use of `kNoSourcePosition` on the `end_position` in the
`ReturnStatement` nodes as indicator to pick the return position from
the function literal, instead of really not putting a source position on
that specific `Return` bytecode.

This CL adds a dedicated marker to `ReturnStatement` to express that the
`BytecodeGenerator` should put the return position from the function
literal there instead of overloading the meaning of `kNoSourcePosition`.
