I found that x86 assembler includes ymm registers, which are 256-bits in length. I am wondering what this will be used in V8.

V8 does not have auto-vectorization, and the simd instructions in V8 all come from webassembly, which only has a `v128` data type. So, how will ymm registers be used in V8?
