__register_frame and __deregister_frame are very slow when called
with many functions many times, like in some of the tests that use
a lot of eval(). Change the approach to interposing a function symbol
that is called in libgcc whenever a PC -> FDE lookup is required.
This also changes the code to create the unwind info on-demand.

Store the platform specific unwind info (CIE/FDE on Linux/Mac x86/x86-64) directly
inside the VM::Function and therefore make all the functions of UnwindHelper static.
Also calculate the function size correctly.

This keeps the C++ implementation code simpler while still providing the same
(pointer based) calling convention.

This is the only place we really need it, as the generic
construct method defined by the spec mainly applies to
functions defined in script.

We need to replace the C++ vtable with a home made one for additional
flexibility. This will help us deal properly with primitive this
values, and allow us to enable certain optimisations where we can
change behavior at runtime (e.g. use optimised lookups as long as
we don't have any accessor properties defined).

We can only do this when getting properties, as setting
values will always happen on the main object.

Fast lookups still require a function call, and will only work
for properties defined on the object itself. Properties of the
prototype will still be slow.

Add an internal class structure to Object that will allow
