Original change's description:
> [csa] use JSGraph to create constants in CodeAssembler
>
> Now that CodeAssembler uses optimizing TurboFan passes, creating
> constants without using the caching implemented in JSGraph leads to
> problems, since value numbering only works properly if all constants
> in the graph were introduced through the cache.
> To mitigate this, this CL creates the JSGraph earlier so that
> CodeAssembler can already use the same JSGraph used by later TurboFan
> optimizations.
> For other uses of RawMachineAssembler, everything stays as before.
