This will immediately remove dead code from the graph once any of
the advanced reducers inserts it. Also changes the GraphReducer to
use the canonical Dead node for ReplaceWithValue.

This makes usage of the MachineOperatorBuilder more robust, as it will be
an error to request an unsupported operator.

Along the way, I noticed that all 7 platforms support Float32Abs and
Float64Abs. Should make them non-optional in another CL?

This API closely matches the Worker API. The differences:

1) The argument to the Worker constructor is a function to run, not a script.
2) Receiving a message from a worker is a synchronous API (as there is no event
loop).

The serialization done here is not robust as the real DOM implementation. For
example, recursive data structures or otherwise duplicated objects are not
allowed.
