Hi Pengfei,
This looks really good, I've just left a couple of small comments below.

Current GCC uses either peeling or versioning, but not in combination,
to handle unaligned data references (DRs) during vectorization. This
limitation causes some loops with early break to fall back to scalar
code at runtime.
Consider the following loop with DRs in its early break condition:
