[vector] ByteBuffer byte ordering

[Lupusoru, Razvan A]

Hi all,

The Vector API uses ByteBuffers internally in several circumstances including resizing, rebracketing, and also exposes methods from reading from and writing to byte buffers. Ideally, the byte ordering should match the native byte ordering so that there is consistency between intrinsification implementation with vector instructions and java implementation.

Please take a look at the patch here:

Thanks,
Razvan
