It turns out that this function didn't make much sense since ReduceTypeOf already dispatches on the type of the input.

Mark null and undefined as undetectable, and use it to handle abstract equality comparison in the generic compare ic Marking as undetectable makes abstract equality of null, undefined, and other undetectable objects easier. Supporting it in the generic compare IC significantly speeds up dynamic comparison between those values and JSReceivers by not falling back to the runtime.

- Introduce a class JSReceiver, that is a common superclass of JSObject and JSProxy. Use JSReceiver where appropriate (probably lots of places that we still have to migrate, but we will find those later with proxy test suite). - Move appropriate methods to JSReceiver class (SetProperty, GetPropertyAttribute, Get/SetPrototype, Lookup, and so on). - Introduce new JSFunctionProxy subclass of JSProxy. Currently only a stub. - Overhaul enum InstanceType: * Introduce FIRST/LAST_SPEC_OBJECT_TYPE that ranges over all types that represent JS objects, and use that consistently to check language types. * Rename FIRST/LAST_JS_OBJECT_TYPE and FIRST/LAST_FUNCTION_CLASS_TYPE to FIRST/LAST_[NON]CALLABLE_SPEC_OBJECT_TYPE for clarity. * Eliminate the overlap over JS_REGEXP_TYPE. * Also replace FIRST_JS_OBJECT with FIRST_JS_RECEIVER, but only use it where we exclusively talk about the internal representation type. * Insert JS_PROXY and JS_FUNCTION_PROXY in the appropriate places. - Fix all checks concerning classification, especially for functions, to use the CALLABLE_SPEC_OBJECT range (that includes funciton proxies). - Handle proxies in SetProperty (that was the easiest part :) ). - A few simple test cases.

This is a first step towards loading globals directly from property cells instead of going through a load IC. This change supports only properties with the DontDelete attribute since we are only able to bailout into the generic code generated by the secondary code generator the beginning of a function. The resulting fast-case code is specialized for a specific context. When invoked with a different global object, it will always bailout to the secondary code. When loading a property that does not exist at compile-time or a property that is deleteable we still generate the generic load IC.

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
