    don't stringify numeric defaults in the inlined codepath

    added extra check in
    Moose::Meta::Method::Constructor::_generate_default_value to return the
    raw default value if it passes looks_like_number($attr->default). This
    fixes the bug where non-lazy attributes with defaults set to numbers
    would be returned as a string instead of a number (i.e. attribute with
    default => 100 would be returned as "100" instead of 100)
