Previously ChangeLowering would always box float64 values when going to tagged representation, but that introduces a lot of deoptimizer loops and polymorphism into TurboFan, which is unfortunate and unnecessary. This adds some logic to ChangeFloat64ToTagged to try harder to create a Smi when going from Float64 to Tagged, instead of always allocating a HeapNumber. This might need some additional tweaking, but at least it makes it possible to start comparing TurboFan and Crankshaft for some regular JavaScript.

Because we track the value of the arguments object, we need to check values whenever plugged into a forbidden value context. It is not enough to check at only variable references as we did previously.

The class did not correctly implement the RequiredInputRepresentation. I changed this functions to be abstract so that all hydrogen classes must implement it. As a convention instructions with zero input operands return None as input representation. Instructions that can handle all input representations without converting before also have None as required input representation (e.g. HTest) All other instructions need a proper required input representation.

If the instanceof stub was requested to deliver true/false objects as the result instead of 0/1 then 0/1 was actually returned if the builtin INSTANCE_OF ended up being called. This is now fixed.

In the shell sample don't print the result of executing a script, only evaluating expressions. Fixed issue when building samples on Windows using a shared V8 library. Added visibility option on Linux build which makes the generated library 18% smaller. Changed build system to accept multiple build modes in one build and generate seperate objects, libraries and executables for each mode. Removed deferred negation optimization (a * -b => -(a * b)) since this visibly changes operand conversion order. Improved parsing performance by introducing stack guard in preparsing. Without a stack guard preparsing always bails out with stack overflow. git-svn-id: http://v8.googlecode.com/svn/branches/bleeding_edge@16 ce2b1a6d-e550-0410-aec6-3dcde31c8c00
