    In the runtime there are specialized fast map routines for
    certain kep types. This CL lets the compiler make use of these
    functions, instead of always using the generic ones.
    
    As we now generate multiple versions of map delete calls, to make
    things easier we delay the expansion of the built-in delete
    function to flatten phase.

    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.
