Icu setText method keeps pointer to text, it doesn't copy it so we have to keep text around for the lifetime of the break iterator object,
or next setText operation.

They do not use subgraphs or subgraph scopes.  Instead of computing a list
of single-block subgraphs and then adding all the edges afterward, build
both the blocks and edges directly.

Before we would compute the flag by iterating over all uses. The truncating 
flag is always determined at construction time since we already computed
the flag for all other instructions before inserting HChange instructions.

In built-in code we use arrays for internal computations.
This makes it possible to affect the built-in code by putting getters
or setters on the Array prototype chain.
This adds a new internal Array constructor that creates Arrays with
a very simplistic prototype chain that doesn't include any publicly
visible objects. These Arrays shoudl ofcourse never leak outside the
builtins, since that would expose the prototype object.
The prototype object contains only the array functions that we use:
push, pop and join (and not even a toString, so it doesn't stringify
well).

Also change uses of .call to %_CallFunction.

SetElement can cause an exception to be thrown. If its return value
isn't checked, this exception might not be handled at the correct time.
In some cases, it's a matter of returning Exception::Failure() from
a runtime function.
In other cases, code using SetElement on a JSArray has been changed
to setting directly on a FixedArray and only creating the JSArray
at the end.

Do not use subgraphs to implement the translation of simple branching
control flow, for the function body entry, or for labeled blocks.

Combine all the loop construction functions into a single one.

Resolve a possible problem with duplicate AST IDs used both for joined loop
break blocks, the normal loop exit, and for their common successor, by never
introducing the extra (successor) block and instead making the normal loop
exit a predecessor of the break join block.  There is a similar issue with
joined continue blocks.

Remove a (never needed) two-element zone list per each time we replace one
hydrogen value with another.

get optimized if there is no GC to promote them, and it does not seem
