c33886c9b7 Change Math.random() to return 32 bits of random goodness, instead of 30 random bits. Math.random now allocates a HeapNumber inline, and calls a C funciton directly to put the random bits into it.

789f832e4a Move the AstVisitor stack check from Accept to Visit. 
The stack check has been moved from the Accept function dispatching on
the AST node type, earlier to the Visit function dispatching on the
visitor type.

This allows very simple non-recursive visitors (not taking extra
arguments or returning values) via the convention of calling "Visit"
if one wants the stack check and "Accept" if one does not.  Recursive
calls should all be via "Visit".

81779f6324 Rework flow graph construction. 
The flow graph has been simplified to remove the special branch, join,
and exit nodes.  All nodes are now basic blocks (possibly empty to
preserve edge-split form) with a distinguished entry and exit block.

Most trivial expressions are not added to the flow graph as
instructions.  The assigned variable analyzer has been changed to
sometimes work right-to-left so that right subexpressions can be
marked as trivial.

The reaching definitions analysis has been temporarily removed, and
the analyses that depended on it (primitivity analysis, dead code
marking) as well.

* Faster hashing for sequential strings.

 * When adding short external two-byte strings try to convert them

   representation even for ascii strings. This optimization saves
