jarin e97b29a4c5 [turbofan] Add type to the allocation operator. 
This gives us more precise type information, so we can avoid some type
guards to refine the type information back.

The motivation for this is to help escape analysis by not introducing
redundant type guards (which escape analysis cannot handle yet even
though it could and should do).

Motivating example:

In the example below, the out-of-object property array for properties
fld5 and fld6 gets type Any when it is created by "o.fld5 = 5" (for
object literals, we store 4 properties in-objeca, the rest goes out
of object).

When we run load elimination for the load the out-of-object property
array (to store 6 into o.fld6), load elimination inserts TypeGuard to
enforce the Type::Internal() type. This makes escape analysis bail out
on this object, and we do not eliminate the object creation.

function f() {
  var o = {};
  o.fld1 = 1;
  o.fld2 = 2;
  o.fld3 = 3;
  o.fld4 = 4;
  o.fld5 = 5;
  o.fld6 = 6;
}

f();
f();
%OptimizeFunctionOnNextCall(f);
f();
