dolby-oss 44e7a02ac3 improve handling of binary expressions

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.

msridhar1 a1a62d4793 Fixed a longstanding bug in the handling of arguments: both v1 _and_ v2 
should be ignored when setting up the arguments array (the former is the
invoked function, the latter is the receiver).

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.

dolby-oss 4da02a9125 Changes to extend supported context sensitivity to CPA-style: 
1) extend ContextSelector interface to allow it to specify parameters of interest
  2) extend filtering mechanism at call sites to allow CPA-style filtering when requested by contexts
  3) various related fixes and extensions:
    a) removed redundant code to handle dispatch for JavaScript, so now it shares the core mechanism
    b) tighten types for operators that take an array of args - now the array is T[] at the cost of a few array allocation methods
    c) a bit more support for empty int sets
    d) void function objects
    e) bug fixes for lexical scoping support, and adaptation to work with core dispatch mechanism
    f) example of CPA-style sensitivity to handle nastiness in a JavaScript for(.. in ...) loop
