fetch_and_$op_$type ptr ~pos val atomically runs *( *$type )((ptr + pos) $op val, stores the result at ptr + pos, and returns the original value at ptr + pos.
Note that pos is a byte offset into the bigstring. If the offset is not a multiple of the target int width in bytes, the operation will be unaligned and potentially *much* slower than the aligned case.
