    Merge #1437
    
    1437: Array index access does not need to unsize to a slice for access r=philberty a=philberty
    
    When we define the core code for SliceIndex access its possible for an
    array to be fully coerced into a slice DST and follow the normal slice
    index access which removes support for GCC -Warray-index checks and
    generates unnessecary code for array access.
    
    Fixes #1436
