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.

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
