We've been running doxygen with the autobrief option for a couple of
years now. This makes the \brief markers into our comments
redundant. Since they are a visual distraction and we don't want to
encourage more \brief markers in new code either, this patch removes
them all.

for i in $(git grep -l '\\brief'); do perl -pi -e 's/\\brief //g' $i & done
By formalizing ReferenceOwnership as a diagnostic argument kind, we get
less boilerplate, better type safety, better output consistency, and
last but not least: future proofing.
If they do provide it, however, it must match. So the following combinations
are valid:
weak var -> override weak var
weak var -> override var
but these are not:
var -> override weak var
weak var -> override unowned var
To be fully correct, we should be cloning the attribute down and adjusting
the type of the overriding property, but I'd rather not touch that right now.

This was part of the original weak design that
there was never any particular reason to rush the
implementation for. It's convenient to do this now
so that we can use it to implement Unmanaged<T> for
importing CF types.

The idea for now is that this is a SIL-only type used for
representing the storage of a weak or unowned reference.
Having it be its own type is pretty vital for reasonable
behavior in SIL and IR-generation, and it's likely that
this will surface into runtime metadata as well (hence
the mangling).
I've implemented a bunch of things that technically I don't
think are necessary if this stays out of the typechecker,
but it's easier to implement half-a-dozen "recurse into
the child type" methods now that it would be to find them
all later if we change our minds.
