As taking a snapshot of a large heap takes noticeable time, it's
good to be able to monitor and control it.

The change itself is small, big code deletes and additions are in
fact moves. The only significant change is simplification of
approximated retained sizes calculation algorithm.

When we have inlined smi code can transition to heap number state before going to the generic state. Without inlined smi code the behaviour is unchanged.

In the case of inlined smi code in non-optimzied code we could not 
distinguish between the smi-only case and the case that the operation was
never executed.

With this change the first execution of a binary operation always jumps
to the stub which in turn patches the smi-check into the correct
conditional branch, so that we benefit from inlined smi code after the
first invocation.

A nop instruction after the call to the BinaryOpIC indicates that no
smi code was inlined. A "test eax" instruction says that there was smi
code inlined and encodes the delta to the patch site and the condition
code of the branch at the patch site to restore the original jump.

SplitBetween (formely known as Split with 3 arguments) should select split position from [start, end] instead of [start, end[. This should also improve allocation quality (remove certain redundant move patterns).

Also some minor renaming and refactoring to make register allocator code more readable.

This is neutral on in-browser SunSpider, but beneficial on other
things, and is likely to lower memory use by collecting earlier.

that ip can be used as a scratch register. This is not true because
ip is already used for something else in AllocateInNewSpace in the
macro assembler.

Explicitly allocate a temp register for use in the heap number
allocation instead.

The expectations are not updated in this change. There are a couple of
bugs that I would like to fix before doing that. Otherwise the lists
