Revert "improve the build performance of vector type built-in function."

This patch still has to be pending to fix the wide integer issue completely.
Although we have a fallback mechanism which will try to build the module again
by ignoring some passes to avoid the wide integer issue, it's broken now on
master branch. As now all the builtin functions have been built statically,
and those bitcode may already have i128/i512 etc.

This reverts commit 565d1eb00d9a5219c2848b3674e40ac07cb48b89.
