RFR: 8304258: x86: Improve the code generation of VectorRearrange with int and float [v3]

[Quan Anh Mai]

> Hi,
> 
> This small patch changes the code generation of VectorRearrangeNode with respect to int and float elements. With not-larger-than-128-bit vectors, we can use `vpermilps` instead of promoting to operating on the extended 256-bit vector. This also helps the code generation of AVX1 to not rely on the sse version.

> Please take a look and leave some reviews.
> Thanks a lot.
