Andreas Kling f558cd9f0d LibJS: Add inline caching for object literal instantiation 
When instantiating an object literal, we go through the list of
properties and add them one by one to the new object. However, we were
totally neglecting to cache the shape transitions incurred by this
process, even though we had allocated a PropertyLookupCache for it.

1.25x speedup on Octane/splay.js and just generally very useful.
