Summary:
Following on from the review for D58088, this patch provides the
prerequisite to_address() implementation that's needed to have
pointer_iterator support unique_ptr.
The late bound return should be removed once we move to C++14 to better
align with the C++20 declaration. Also, this implementation can be removed
once we move to C++20 where it's defined as std::to_addres()
The std::pointer_traits<>::to_address(p) variations of these overloads has
not been implemented.

to reflect the new license.
We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.
Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

This allows us to model the common LLVM idiom of incrementing
immediately after dereferencing so that we can remove or update the
entity w/o losing our ability to reach the "next".
However, these are not real or proper iterators. They are just enough to
allow range based for loops and very simple range algorithms to work,
but should not be considered full general.

r327219 added wrappers to std::sort which randomly shuffle the container before
sorting. This will help in uncovering non-determinism caused due to undefined
sorting order of objects having the same key.
To make use of that infrastructure we need to invoke llvm::sort instead of
std::sort.
Note: This patch is one of a series of patches to replace *all* std::sort to
llvm::sort. Refer the comments section in D44363 for a list of all the
required patches.

This adds support for ADL in the range based <algorithm> extensions
(llvm::for_each etc.).
Also adds the helper functions llvm::adl::begin and llvm::adl::end which wrap
std::begin and std::end with ADL support.
Saw this was missing from a recent llvm weekly post about adding llvm::for_each
and thought I might add it.

There were some issues in the implementation of enumerate()
preventing it from being used in various contexts. These were
all related to the fact that it did not supporter llvm's
iterator_facade_base class. So this patch adds support for that
and additionally exposes a new helper method to_vector() that
will evaluate an entire range and store the results in a
vector.

This recommits r290512 that was reverted when MSVC failed to compile it. Since
then I've played with various approaches using rextester.com (where I was able
to reproduce the failure) and think that I have a solution thanks in part to
the help of Dave Blaikie! It seems MSVC just has a defective `decltype` in this
version. Manually writing out the type seems to do the trick, even though it is
.... quite complicated.
Original commit message:
This allows both defining convenience iterator/range accessors on types
which walk across N different independent ranges within the object, and
more direct and simple usages with range based for loops such as shown
in the unittest. The same facilities are used for both. They end up
quite small and simple as it happens.
I've also switched an iterator on `Module` to use this. I would like to
add another convenience iterator that includes even more sequences as
part of it and seeing this one already present motivated me to actually
abstract it away and introduce a general utility.

This code doesn't work on MSVC for reasons that elude me and I've not
yet covinced a workaround to compile cleanly so reverting for now while
I play with it.

llvm::cl already has a function called llvm::apply() so this is
causing an ODR violation. The STLExtras version should win the
vote on which one gets to be called apply() since it is named
after the equivalent STL function, but since renaiming the cl
version is more difficult, let's do this for now to get the
bots green.

The CL was originally failing due to the use of some C++14
specific features, so I've removed those. Hopefully this will
satisfy the bots.

enumerate allows you to iterate over a range by pairing the
iterator's value with its index in the enumeration. This gives
you most of the benefits of using a for loop while still allowing
the range syntax.

This is a little class template that just builds an inheritance chain of
empty classes. Despite how simple this is, it can be used to really
nicely create ranked overload sets. I've added a unittest as much to
document this as test it. You can pass an object of this type as an
argument to a function overload set an it will call the first viable and
enabled candidate at or below the rank of the object.
I'm planning to use this in a subsequent commit to more clearly rank
overload candidates used for SFINAE. All credit for this technique and
both lines of code here to Richard Smith who was helping me rewrite the
SFINAE check in question to much more effectively capture the intended
set of checks.
