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
