             nThis:


According to the opcode sampler, the creation of new function objects is 8% of
total time on the V8 Earley-Boyer benchmark. One of the things that stands out
here is that three properties are added to every new JSFunction using
putDirect(). We should make the addition of these properties more efficient in
a similar fashion to the way the creation of singleton objects uses fewer
StructureIDs.
