support “new, delete, in, instanceof” keywords

[i7soft]

i add "in,instanceof" to binary_ops object,like:

binary_ops = {
			'in':0,'instanceof':0,
			'||': 1, '&&': 2, '|': 3,  '^': 4,  '&': 5,
			'==': 6, '!=': 6, '===': 6, '!==': 6,
			'<': 7,  '>': 7,  '<=': 7,  '>=': 7,
			'<<':8,  '>>': 8, '>>>': 8,
			'+': 9, '-': 9,
			'*': 10, '/': 10, '%': 10
		},

but how to support "new" and "delete" keywords？
like: new Date().valueOf(), first step should call "new Date",then call "valueOf"

{
    "type": "Compound",
    "body": [
        {
            "type": "Identifier",
            "name": "new"
        }, {
            "type": "CallExpression",
            "arguments": [],
            "callee": {
                "type": "MemberExpression",
                "computed": false,
                "object": {
                    "type": "CallExpression",
                    "arguments": [],
                    "callee": {
                        "type": "Identifier",
                        "name": "Date"
                    }
                },
                "property": {
                    "type": "Identifier",
                    "name": "valueOf"
                }
            }
        }
    ]
}

like:delete a.b

{
    "type": "Compound",
    "body": [
        {
            "type": "Identifier",
            "name": "delete"
        }, {
            "type": "MemberExpression",
            "computed": false,
            "object": {
                "type": "Identifier",
                "name": "a"
            },
            "property": {
                "type": "Identifier",
                "name": "b"
            }
        }
    ]
}

You can add them as unary ops.
