Support for it is slow and difficult to implement, and it's not used in
Blink. An embedder that uses this feature will have to check the
argument types itself.

Since we have a special guard page at the beginning of the code range on
win64, we need to make sure to adjust the size of the free list
accordingly when creating it.

(Debug builds have --enable-slow-asserts, and with slow asserts each
assignment to the array in the prepare function will trigger a check
over the entire array. This turns it into n^2 work, for reasonably
large n.)

- Move NodeMarker to its own file, and introduce a non
templatized base class.
- Cleanup the include hell.
- Sanitize the Node construction methods now that we
got rid of that GenericNode/GenericGraph stuff.
- Protect against NodeId overflow in Graph.
- Various minor cleanups.

Introduce a new AnyToBoolean simplified operator to handle the later
lowering of boolean conversions. Previously we tried to hack that with
the generic JSToBoolean, having its context set to zero, but that lead
to various problems/bugs and did not handle all cases.

We cannot just clear the result register optimistically, because the
register allocator might assign the same register to result and buffer.

Change InstructionOperand to use a 64-bit field for encoding the operand
information instead of the 32-bit field that was used before. Ideally we
wouldn't use the Zone-allocated bit field at all, and use an integer
instead of the pointer; but that requires fixing the register allocator
first, which will take some time.
