Manu Sridharan 11c6619c7f Variety of changes to JS front end. 
- crash fixes
- small enhancements to prologue and preamble
- tighter handling of timeouts during CG construction
 2013-04-09 15:47:22 -07:00
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

Manu Sridharan 6084f4ff61 Generate proper InstanceFieldKeys for property accesses with Numbers. 
Note that this change actually breaks a couple of our unit tests.  But,
it seems they were only passing by accident before anyway, and this change
at least leads to a more consistent handling of dynamic property accesses
with String vs. Number property names.

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 5bc7fb3e44 Within for/in bodies, use a marker for/in context instead of a CallerSiteContext 
to better handle certain recursion.  Still needs better Javadoc

msridhar1 a840e068d6 When extracting correlated pairs, check that the extraction region does 
not reference the "arguments" variable.

msridhar1 a3d0b45eef Added support for localising variables through which correlated reads 
flow. This somewhat compensates for the lack of SSA form for closure
variables under the new lexical scheme.

msridhar1 92d8dc1e3d Revert "refactor context selectors: extract delegation into ComposedContextSelector" 
This reverts commit 7ff1219c5baed388a82d14fcf81d2b1f456c4e95.  That commit broke
a dojo test, and I'm not sure why.
