Three misc updates that are needed for SpiderMonkey's prototype of the GC proposal.

dataref is gone, there is now structref re-using the binary encoding of datarefr
extern.{internalize, externalize} are new instructions
array.len no longer has a type immediate, and has a new encoding

There are other changes in the latest V8 milestone we're tracking, but we're not ready to support them yet.
