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.

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.

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.

2. The buffer allocated in one of the constructors of the

and sometimes doesn't (if it was passed one). Simple fix is to
