Introducing a virtual-frame-inl.h file containing some platform-independent
virtual frame function which are small enough to be inlined.

Removed unnecessary #include of virtual-frame.h from register-allocator-inl.h
and added the necessary explicit includes in a number of files.

Each frame element gets a new attribute with number type information. A frame element can be: 

- smi 
- heap number 
- number (i.e. either of the above) 
- or something else. 

The type information is propagated along with all virtual frame operations. 
Results popped from the frame carry the number information with them.

Two optimizations in the code generator make use of the new 
information: 
- GenericBinaryOpSyub omits map checks if input operands are numbers. 
- Boolean conversion for numbers: Emit inline code for converting a number (smi or heap number) to boolean. Do not emit call to ToBoolean stub in this case.

The complexity of static type inference never really paid off, and as an
analysis it didn't fit well with codegen frame propagation.

This issue was raised by Brett Wilson while reviewing my changelist for readability. Craig Silverstein (one of C++ SG maintainers) confirmed that we should declare one namespace per line. Our way of namespaces closing seems not violating style guides (there is no clear agreement on it), so I left it intact.

stack pointer to change by more than one in a corner case.  If we push
a constant smi larger than 16 bits, we push it via a temporary
register.  Allocating the temporary can cause a register to be spilled
from the frame somewhere above the stack pointer.

As a fix, do not use pushes to materialize ranges of elements of size
larger than one.

we dispatched on the IC stub kind in a generic CallCodeObject
function.  Now, we have special functions for the load and store IC
stubs.

We also (for the load and store ICs) handle moving register arguments
into place only after the stack is prepared for the call.  This
replaces some memory-to-memory moves (for copies whose backing store
is occupied by a register needed for the arguments) with
memory-to-register moves.
