8d46932137 Fix whitespace in vectorizer example

6a7d263e8b Fix vectorizer docs. 
This example is not vectorized because LLVM does not prove no-wrapping of
"a[i*7] += ...".

6241703ee4 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.
