Could you take a look, please?

I am especially interested in your opinion on what to do with the
LoweringResult: 

- do you think all the js-type-hint-lowering methods use LoweringResult?

- I am not really happy about the structuring of work between
TryBuildSimplifiedLoadNamed and VisitLdaNamedProperty each do a bit of the
re-wiring work, but I kept it this way to be consistent with other early
lowerings. How would you feel about shifting the ApplyEarlyReduction work to
VisitLdaNamedProperty>
