A specialized version of `baseIsEqualDeep` for comparing objects of
the same `toStringTag`.

**Note:** This function only supports comparing values with tags of
`Boolean`, `Date`, `Error`, `Number`, `RegExp`, or `String`.

@private
@param {Object} object The object to compare.
@param {Object} other The other object to compare.
@param {string} tag The `toStringTag` of the objects to compare.
@param {Function} equalFunc The function to determine equivalents of values.
@param {Function} customizer The function to customize comparisons.
@param {number} bitmask The bitmask of comparison flags. See `baseIsEqual`
 for more details.
@param {Object} stack Tracks traversed `object` and `other` objects.
@returns {boolean} Returns `true` if the objects are equivalent, else `false`.
