Addressing modes in `mov`, and their C version

Below are addressing modes (immediate, register, memory) on the examples of the mov assembly instruction. Here we use movl ("move long") for a 32-bit word.

Note: cannot move memory-to-memory, need two instructions.

movl

	// See http://www.bluejava.com/4NS/Speed-up-your-Websites-with-a-Faster-setTimeout-using-soon
	// This is a very fast "asynchronous" flow control - i.e. it yields the thread and executes later,
	// but not much later. It is far faster and lighter than using setTimeout(fn,0) for yielding threads.
	// Its also faster than other setImmediate shims, as it uses Mutation Observer and "mainlines" successive
	// calls internally.
	// WARNING: This does not yield to the browser UI loop, so by using this repeatedly
	// you can starve the UI and be unresponsive to the user.
	// Note: For an even faster version, see https://gist.github.com/bluejava/b3eb39911da03a740727
