    When converting a constant to interface, such as interface{}(42)
    or interface{}("hello"), if the interface escapes, we currently
    generate a heap allocation to hold the constant value.
    
    This CL changes it to generate a static allocation instead, as
    the gc compiler does. This reduces allocations in such cases.
