binary constants are not accepted

Binary const declaration like const b = 0b100 does not work.

package main

import (
	"fmt"
)

func main() {
	const a = 100
	const b = 0b100

	fmt.Println(a + b)
}

This code reports an error message while it should run properly:

9:13: expected ';', found 'IDENT' b100 (and 2 more errors)
