Arnold Schwaighofer 6ccda923e5 LTO: Add the loop vectorizer to the LTO pipeline. ...

During the LTO phase LICM will move loop invariant global variables out of loops
(informed by GlobalModRef). This makes more loops countable presenting
opportunity for the loop vectorizer.

Adding the loop vectorizer improves some TSVC benchmarks and twolf/ref dataset
(5%) on x86-64.
