RFR: 8353551: C2: Constant folding for ReverseBytes nodes [v6]

Fri Apr 25 08:55:30 UTC 2025

> This change implements constant folding for ReverseBytes nodes.
> 
> Currently, `byteswap` is included transitively by `reverse_bits.hpp`. I'm not sure if this is fine or if I need to add an explicit include there.
> 
> I appreciate any reviews and comments.
