98b93c739d Added support for expression statements to the CFG builder and 
fast-mode compiler.

This will generate a compiler temporary for complex expressions and
then immediately throw it away, so a better approach (to be
implemented later) is to pass to the expression builder whether an
expression is in an effect or value context.

23fbd8fe3f Add support to the CFG builder for non-short-circuited binary 
expressions.  Add compilation support in fast mode (optimized for
compilation time and code size).

This breaks one debugger test each on ARM and IA32 (expectedly).

5470f9b132 Add an ability to initiate GC through V8 API. 
I'm planning to use it in DevTools heap profiler. It is a common scenario in debugging memory leaks to enforce GC, then perform an operation, then enforce GC again to check for non-collected (that is, leaked) objects. Using the existing GC extension isn't possible because it doesn't exposed in the normal operation mode of Chromium.

  During the simple style fix I discovered that this whole routine was

  realized that the function was also skipping entries if there were two

cffc051177 Avoid dictionary expansion during bootstrapping. 
Allocate the code stubs dictionary and non monomorphic cache dictionary with an initial size which avoids these dictionaries to be expanded during bootstrapping. This gets rid of 9 dictionary expansions during bootstrapping.

Preallocate the dictionary when normalizing an object to a size sufficient for holding the number of properties which is expected to be added to the object. This is used when ceating an object from an object literal boilerplate where multiple properties are known to be added.  This gets rid of 10 dictionary expansions during bootstrapping.

There are now 3 dictionary expansions left during bootstrapping.

98425a31f1 Speed up CalledAsConstructor. 
Changed CalledAsConstructor to process the raw runtime stack directly,
rather than using a StackFrameIterator.  Using an interator turns out
to be quite expensive and the vast majority of the work done is not
relevant to deciding if we've been called as a constructor.

This speeds up getElementById by ~13%.

e97554ed10 Add generic V8 API functions for controlling profiling aspects. 
As we'll have several aspects of heap profiling, it is more handy to control them using binary flags than by individual functions. CPU profiling represent just a particular aspect to control, so {Pause,Resume}Profiler and IsProfilerPaused are only left for compatibility.

For now, PROFILER_FLAG_HEAP_STATS and PROFILER_FLAG_JS_CONSTRUCTOR are equivalent, but later will be split.

9e8216ef22 Introduce first approximation of constructor heap profile for JS objects. 
It is activated with '--log-gc' flag.

JS object size is calculated as its size + size of 'properties' and 'elements' arrays, if they are non-empty. This doesn't take maps, strings, heap numbers, and other shared objects into account.

As Soeren suggested, I've moved ZoneSplayTree from jsregexp to zone, and removed now empty jsregexp-inl header file.
