<pre>Add Math.trunc's TruncIntrinsic and DFG ArithTrunc.
And use @trunc in toInteger. (This is the same in JSValue::toInteger)
Currently, even if we know the given value is Int32, due to @abs and negation, we always emit some code.
But if we add it, we can convert them to Identity in DFG Fixup phase.</pre>
