This patch LGTM, although just as we discussed, this patch
will not accelerate most of the builtin vector function's
compilation. As those functions are precompiled with normal
optimization options, and the for loop will be unrolled by
default.
We may need to change the precompilation logic and don't
use the default compilation option in the future.
