Some DOM operations are very tiny operation. For example, firstChild just looks up the stored member from Node*.
In these cases, DOM binding code itself occupies large part of execution time.

We would like to optimize DOM binding further by implementing DOM binding code in special IR.
And this IR will be handled in JSC DFG, and they should be correctly inlined.
