Julian Dolby 9aa474fdb1 1) added InstanceKey.getCreation sites and its implementations 
2) fixes for issues with keys representing dynamic properties
  i) all properties are converted to strings, in an approximation of JS
semantics
3) fix to handling of instance keys representing numbers in binary +;
now it understands that adding constant keys of type Number requires
adding a non-constant Number key to the lval

dolby-oss a9ec87f360 Changes motivated by analysis issues in JavaScript. The main change is that calls of the form f.x() in JavaScript are now analyzed like 'method calls' so that the 'this' pointer in the receiver functions can be filtered based upon the types that actually have the method being invoked. This requires much more dynamic filtering than in a language like Java, since properties like 'x' are simply properties that happen to hold functions, and so can be assigned in a first-class manner. Thus, the filtering needs to handle variance in both the types and the values of their properties; this is implemented as multiple levels of abstract object directed side effect equations in the dataflow system.

dolby-oss 4c6d062dbb blunt force trauma to CAst frond end: 
1) Structural changes in the AstTranslator to allow retranslation and generation of custom IR.  This is mostly moving state from the translator itself into the context.
2) Some refactoring to share some AST generation code across the Java and JavaScript front ends.
3) Switching to the latest Rhino, release 1.7R3; this is a pervasive change to the JavaScript Rhino translator, since it involves switching to the new AST interface in Rhino.
4) Common code to, as an option, translate Do-style loops by replicating the loop body.  This allows the use of CAstNode.LOOP forms for such loops.
5) Some bug fixes to the mechanisms of the CAstRewriter to handle weird control flow cases.
6) An example of retranslation to specialize JavaScript methods based on how many arguments they receive at call sites.

yinnon_haviv 38f8a44044 Fix prototype contamination bug (described in added test). 
When someone writes: 
MyFunction.prototype.myMethod = ...
we want "myMethod" to be accessible only for objects of type "MyFunction".

- Change how generated ctors look like - now they have a private prototype object into which methods can be added
- Change the PropertyReadExpander to have a different handling when reading the "prototype" field, avoid performing a loop on the prototype chain, so that the points to set of fetched field will be accurate (and allow us to set only the fields of it)
