Original issue's description:
> [turbofan] Less aggressively insert SOFT deopts for property access.
>
> Sometimes TurboFan is able to extract receiver maps from the surrounding
> graph and thus is able to generate reasonable code for property accesses,
> even if those haven't been executed in the baseline tier yet. So, only
> stick in an SOFT deoptimization exit, if ExtractReceiverMaps failed to
> infer proper receiver maps.
