  [JetStream2] Always instantiate Float32Array in the cost array of findOptimalSegmentationInternal.
https://bugs.webkit.org/show_bug.cgi?id=267436

Reviewed by Yusuke Suzuki.

The cost array in findOptimalSegmentationInternal is always intended to be an array of Float32Array
but we were forgetting to instantiate Float32Array for the very first item in the array.

This PR makes it more consistent across the array.
