Description Luke Wagner [:luke] 2012-07-17 15:54:25 PDT
With bug 753158, JSOP_NAME will only show up when there is dynamic scoping (eval/with/non-compile-n-go-global).  Name ICs in JM/IM should cover hot uses of JSOP_NAME.  This means there should be very little need for the property cache in JSOP_NAME.  Removing this use should allow us to stop setting delegates, setting extensibleParents, and generating own shapes in case of extensibleParents.

I had no idea how much grossness this entailed.
