Fills all elements within a portion of an accessor array with a specified value.

@private
@param {Object} x - input array object
@param {*} value - fill value
@param {integer} start - starting index (inclusive)
@param {integer} end - ending index (exclusive)
@returns {AccessorArray} modified input array

@example
var toAccessorArray = require( '@stdlib/array/base/to-accessor-array' );
var arraylike2object = require( '@stdlib/array/base/arraylike2object' );

var x = toAccessorArray( [ 1, 2, 3, 4 ] );
var obj = arraylike2object( x );

var out = accessors( obj, 5, 1, 3 );
// returns <AccessorArray>

var v = x.get( 0 );
// returns 1

v = x.get( 1 );
// returns 5

v = x.get( 2 );
// returns 5

v = x.get( 3 );
// returns 4
