Bigstring (ocaml_simd.ocaml_simd.avx.Ocaml_simd

WARNING: by default, the backing array of a bigstring is allocated by `malloc`, so is only 16-byte aligned. The aligned operations below require 32-byte alignment.

Note the safe aligned operations can be used to determine the offset at which a bigstring becomes 32-aligned.
