Splits values into two groups according to a predicate function and outputs results as object values.

## Notes

-   We need to cache the object value to prevent the edge case where, during the invocation of the predicate function, the value at key `k` is swapped for some other value. For some, that might be a feature; here, we take the stance that one should be less clever.

@private
@param {(Object|Array|TypedArray)} obj - input object
@param {Options} opts - function options
@param {*} [opts.thisArg] - execution context
@param {Function} predicate - predicate function indicating which group an element in the input object belongs to
@returns {(Array<Array>|Array)} results

@example
function predicate( v ) {
    return v[ 0 ] === 'b';
}
var obj = {
    'a': 'beep',
    'b': 'boop',
    'c': 'foo',
    'd': 'bar'
};
var out = bifurcateOwn( obj, {}, predicate );
// e.g., returns [ [ 'beep', 'boop', 'bar' ], [ 'foo' ] ]
