Arnold Schwaighofer 34ac9be1d7 Fix vectorizer docs.
This example is not vectorized because LLVM does not prove no-wrapping of
"a[i*7] += ...".

Sean Silva 08fd0888cb docs: Clean up adornments.
For whatever reason the usage of '^^^' and '---' adornments were
reversed compared to the "canonical" style of the LLVM docs (which is
currently "the style used in SphinxQuickstartTemplate.rst"). This change
doesn't affect the document structure at all, I'm just doing it for
trivial stylistic consistency (the document content is *much* more
important---thanks Nadav for writing this up!).

Also, trim the adornments to be the same length as the section names.
