This is another case of conditional ownership (in this case a raw
reference, plus a boolean to indicate whether the referenced object
should be deleted). While it's not ideal, I prefer to make the ownership
explicit with a unique_ptr than using a boolean flag (though it does
make the reference and the unique_ptr redundant in the sense that they
both refer to the same memory). At some point we might write a reusable
conditional ownership pointer (a stateful custom deleter for a unique_ptr
may be appropriate).
Based on a patch from a patch by Anton Yartsev.

A 'remark' is information that is not an error or a warning, but rather some
additional information provided to the user. In contrast to a 'note' a 'remark'
is an independent diagnostic, whereas a 'note' always depends on another
diagnostic.
A typical use case for remark nodes is information provided to the user, e.g.
information provided by the vectorizer about loops that have been vectorized.
This patch provides the initial implementation of 'remarks'. It includes the
actual definiton of the remark nodes, their printing as well as basic parameter
handling. We are reusing the existing diagnostic parameters which means a remark
can be enabled with normal '-Wdiagnostic-name' flags and can be upgraded to
an error using '-Werror=diagnostic-name'. '-Werror' alone does not upgrade
remarks.
This patch is by intention minimal in terms of parameter handling. More
experience and more discussions will most likely lead to further enhancements
in the parameter handling.

uncovered.
This required manually correcting all of the incorrect main-module
headers I could find, and running the new llvm/utils/sort_includes.py
script over the files.
I also manually added quite a few missing headers that were uncovered by
shuffling the order or moving headers up to be main-module-headers.

the various stakeholders bump up the reference count. In particular,
the diagnostics engine now keeps the DiagnosticOptions object alive.

we have the ability to create a new, distict diagnostic consumer when
we go off and build a module. This avoids the currently horribleness
where the same diagnostic consumer sees diagnostics for multiple
translation units (and multiple SourceManagers!) causing all sorts of havok.
