Add a new attribute, 'noduplicate'. If a function contains a noduplicate call, the call cannot be duplicated - Jump threading, loop unrolling, loop unswitching, and loop rotation are inhibited if they would duplicate the call.

Similarly inlining of the function is inhibited, if that would duplicate the call (in particular inlining is still allowed when there is only one callsite and the function has internal linkage).

This is a pretty lengthy document, so put the table of contents in your
face so that it's easier to scope out the content.

This document is a mess currently and needs to be
refactored/revised/split-up.

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.

Building Vectorizers.rst produces a few warnings of the form:

   WARNING: Title underline too short.

Fixed by adding the extra needed dashes under the title.

will look a bit different when we have time to get it ready to turn on,
and we won't likely need this reminder.

If anyone has better highlights (I'm obviously biased by the things that
I'm excited about) jump in and add them!
