Dead code elimination of inlined arguments objects causes wrong deopt info to be generated - instead of materializing the arguments, we get 'undefined'.

Golem says the change is perf-neutral.

OrderedHashTable is an insertion-ordered HashTable based on
Jason Orendorff's writeup of a data structure attributed to Tyler Close:
https://wiki.mozilla.org/User:Jorend/Deterministic_hash_tables

It is intended as the new backing store for JSSet/JSMap, as ES6 requires
insertion-order-based iteration. Note, however, that in the interest of
keeping the initial check-in small this patch does not yet include any
iteration support.

This change also doesn't yet touch any existing behavior, but in
a branch I've verified that these structures pass the existing
JSSet/JSMap mjsunit tests.
