    compiler: typing fixes for Interface_mtable_expression
    
    Interface_mtable_expression::do_type computes a type that incorporates
    Go type descriptors for the interface methods, whereas in order to
    have strict type agreement with the mtable data, the interface method
    fields need to be C function ptrs. Change the type recipe accordingly,
    and then update Interface_mtable_expression::do_get_backend to compute
    a revised backend type that uses the correct fcn types.
