9cf3909975 Track field types. 
This is an initial step towards tracking the exact types instead of just the representations of fields. It adds support to track up to one map of heap object field values, eliminating various map checks on values loaded from such fields, at the cost of making stores to such fields slightly more expensive.

2e9902b22a Partially fix semantics of Array.push() 
Semantics of elements accessors are now preserved in all optimized code paths
through Array.push(). Previously it was possible to have inconsistent behavior
between optimized and unoptimized code, and there were cases where element
accessors were completely ingored.

5bddec047d Do not use ranges after range analysis. 
Due to the SSA vs. SSI difference, we are only allowed to use the
flags computed during range analysis, not the ranges themselves. For
the case at hand, there is no such flag, so the condition is simply
remvoed.

5a564648dd Improve reproducibility of test runs. 
Add random seed to run-tests.py, using either a user supplied
value or a random number generated by random.SystemRandom().
This same random seed is passed to all test cases, making sure
that we can easily reproduce test failures that depend on
random numbers (i.e. bugs related to our handwritten ASLR).

Also fix all uses of rand() to make use of our RNG class
instead.

c2bbd9f9e2 Don't pass the hole to SetElement when creating Array.observe change records 
Also added comments to remind us why we were using the hole here in the first

has been called on Array that's undergoing truncation).
