Critical edges going into a loop are not as bad as critical exits. We can handle
them by splitting the critical edge, or by having both inside and outside
registers live out of the predecessor.

      - Try to reduce logging to one line per function call instead of tw
      - Put all arguments & their values into log for calls
      - Add 'this' parameter information to function call logging, making it show the appropriate
        internal pointer (this.obj, this.sp, this.ap...)
      - Clean up some return values
      - Remove logging of constructors that construct empty objects
      - Change '==>' to '=>'  for showing result values...
      - Fix various minor bugs
      - Add some protected 'get' functions to help getting the internal pointers for the 'this' arguments...

explicit about the operands. Split out the different variants into separate
instructions. This gives us the ability to, among other things, assign
different scheduling itineraries to the variants. rdar://8477752.

the remainder register.

Example:

bb0:
  x = 1
bb1:
  use(x)
  ...
  x = 2
  jump bb1

When x is isolated in bb1, the inner part breaks into two components, x1 and x2:

bb0:
  x0 = 1
bb1:
  x1 = x0
  use(x1)
  ...
  x2 = 2
  x0 = x2
  jump bb1
