Benchmarks "Google has released a research paper that suggests C++ is the best-performing programming language in the market. The internet giant implemented a compact algorithm in four languages - C++, Java, Scala and its own programming language Go - and then benchmarked results to find 'factors of difference'."

I couldn't tell you more about GCC vectorisation in any great detail.

I have seen restrict et al work (that is generate vector code) on ARM for the NEON instruction set but right now I can't remember if that was RVCT or GCC. If ARM is your thing it might be worth checking the linaro.org builds of GCC. For x86 - I'm afraid I've no idea. I just hit "build" in Qt Creator as none of my x86 code is really that performance critical anymore!
