mstarzinger 3cc2adb319 [deoptimizer] Fix materialization of sloppy arguments.
This makes sure the deoptimizer can materialize sloppy arguments objects
with the FAST_SLOPPY_ARGUMENTS_ELEMENTS elements kind. TurboFan's escape
analysis treates those as normal JSObject types and hence materializes
them differently than Crankshaft does.
