Move work to omit unnecessary ObjectLiteral stores to the numbering pass.

Move work to omit unnecessary ObjectLiteral stores to the numbering pass.

The reason is that this information will be needed to compute the number of
vector ic slots done at numbering time.

Hi Jakob, here is something I'll need in order to calculate the required number
of store ic slots for object literals. We have some work done at compile time
that needs to move to numbering.

I'd like to land this small CL and verify there aren't performance issues for
moving this forward in the pipeline.
Thx for the look,
--Michael
