fschneider@google.com b42a49f107 Fix a bug in SSA renaming. 
This CL changes the order of step 2a and 2b in the SSA renaming: Uses of
LoadLocal/StoreLocal must be renamed first so that the environment is correctly
updated for StoreLocal instructions.

A simple example showing the bug:

test_xy() {
  var x = 1;
  var y = 2;
  var z = 3;
  for (var i = 0; i < 5; i++) {
    y = z = x;
    x++;
  }
  return x + y + z;
}

Also in this change:
- changed the printing of SSA operands to v0, v1, .. instead
of t0, t1 to better distinguish them from non-SSA operands.
- make sure that UseVal are always copied when renaming phi 
input operands.

fschneider@google.com 123bfe4e08 Second step for computing SSA: renaming. 
This CL adds the renaming step to the SSA construction. The renaming pass
initializes a start environment with the initial values of all locals (#null)
 and parameters and removes LoadLocal and StoreLocal instructions from the
 graph.

Right now the renaming does not support functions with parameters yet.
I added a TODO for this. The SSA form for a simple function with an if-statement:

function foo() {
  var v = 0;
  var x;
  if (v == 0) {
    x = 42;
  }
  return x;
}

looks as follows:

 0: [graph]
  #null
  #null
 1: [target]
    t0 <- #0
    t1 <- #null
    t2 <- #0
    t3 <- EqualityCompare(t0 == t2)
    Branch if t3 goto (2, 3)
 2: [target]
    t5 <- #42 goto 4
 3: [target] goto 4
 4: [join]
    t4 <- phi(t1,t5)
    Return t4

- when resolving the native method which has been closurized account for the 'this' argument in the count of arguments.
- explicitly copy the 'this' parameter in the closure context as the first parameter before calling the native function. This is done by piggy backing on the CopyParameters code used for functions with optional parameters.
