Returns the index of the last element which equals a provided search element according to the same value algorithm.

@private
@param {Object} x - input array object
@param {*} searchElement - search element
@param {NonNegativeInteger} fromIndex - starting index (inclusive)
@returns {integer} index

@example
var toAccessorArray = require( '@stdlib/array/base/to-accessor-array' );

var x = toAccessorArray( [ 1, 2, 3, 4 ] );

var idx = accessors( x, 2, 3 );
// returns 1
