Fix for ​https://bugs.webkit.org/show_bug.cgi?id=21683
Don't create intermediate StructureIDs for builtin objects

Second stage in reduce number of StructureIDs created when initializing the
JSGlobalObject.

• Use putDirectWithoutTransition for the remaining singleton objects to reduce the number of StructureIDs create for about:blank from 132 to 73.
