/**
* Simultaneously sorts two double-precision floating-point strided arrays based on the sort order of the first array using heapsort.
*
* @param {PositiveInteger} N - number of indexed elements
* @param {number} order - sort order
* @param {Float64Array} x - first input array
* @param {integer} strideX - stride length for `x`
* @param {NonNegativeInteger} offsetX - starting index for `x`
* @param {Float64Array} y - second input array
* @param {integer} strideY - stride length for `y`
* @param {NonNegativeInteger} offsetY - starting index for `y`
* @returns {Float64Array} `x`
*
* @example
* var Float64Array = require( '@stdlib/array/float64' );
*
* var x = new Float64Array( [ 1.0, -2.0, 3.0, -4.0 ] );
* var y = new Float64Array( [ 0.0, 1.0, 2.0, 3.0 ] );
*
* dsort2hp( x.length, 1.0, x, 1, 0, y, 1, 0 );
*
* console.log( x );
* // => <Float64Array>[ -4.0, -2.0, 1.0, 3.0 ]
*
* console.log( y );
* // => <Float64Array>[ 3.0, 1.0, 0.0, 2.0 ]
