6b547686c5 Update the file headers across all of the LLVM projects in the monorepo
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.

6bc5d6199d [unittests] ADT: silence -Wself-assign diagnostics
Summary:
D44883 extends -Wself-assign to also work on C++ classes.
In it's current state (as suggested by @rjmccall), it is not under it's own sub-group.
Since that diag is enabled by `-Wall`, stage2 testing showed that:
* It does not fire on any llvm code
* It does fire for these 3 unittests
* It does fire for libc++ tests

This diff simply silences those new warnings in llvm's unittests.
A similar diff will be needed for libcxx. (`libcxx/test/std/language.support/support.types/byteops/`, maybe something else)

Since i don't think we want to repeat rL322901, let's talk about it.
I've subscribed everyone who i think might be interested...

There are several ways forward:
* Not extend -Wself-assign, close D44883. Not very productive outcome i'd say.
* Keep D44883 in it's current state.
  Unless your custom overloaded operators do something unusual for when self-assigning,
  the warning is no less of a false-positive than the current -Wself-assign.
  Except for tests of course, there you'd want to silence it. The current suggestion is:
  ```
  S a;
  a = (S &)a;
  ```
* Split the diagnostic in two - `-Wself-assign-builtin` (i.e. what is `-Wself-assign` in trunk),
  and `-Wself-assign-overloaded` - the new part in D44883.
  Since, as i said, i'm not really sure why it would be less of a error than the current `-Wself-assign`,
  both would still be in `-Wall`. That way one could simply pass `-Wno-self-assign-overloaded` for all the tests.
  Pretty simple to do, and will surely work.
* Split the diagnostic in two - `-Wself-assign-trivial`, and `-Wself-assign-nontrivial`.
  The choice of which diag to emit would depend on trivial-ness of that particular operator.
  The current `-Wself-assign` would be `-Wself-assign-trivial`.
  https://godbolt.org/g/gwDASe - `A`, `B` and `C` case would be treated as trivial, and `D`, `E` and `F` as non-trivial.
  Will be the most complicated to implement.

Thoughts?

77a1dcd15b [unittests] Change std::sort to llvm::sort in response to r327219
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.

3c0d60785c Re-sort #include lines for unittests. This uses a slightly modified
clang-format (https://reviews.llvm.org/D33932) to keep primary headers
at the top and handle new utility headers like 'gmock' consistently with
other utility headers.

No other change was made. I did no manual edits, all of this is
clang-format.

This should allow other changes to have more clear and focused diffs,
and is especially motivated by moving some headers into more focused
libraries.

cb8ffd254b ADT: Fix SmallPtrSet iterators in reverse mode
Fix SmallPtrSet::iterator behaviour and creation ReverseIterate is true.

  - Any function that creates an iterator now uses
    SmallPtrSet::makeIterator, which creates an iterator that
    dereferences to the given pointer.

  - In reverse-iterate mode, initialze iterator::End with "CurArray"
    instead of EndPointer.

  - In reverse-iterate mode, the current node is iterator::Buffer[-1].
    iterator::operator* and SmallPtrSet::makeIterator are the only ones
    that need to know.

  - Fix the assertions for reverse-iterate mode.

This fixes the tests Danny B added in r297182, and adds a couple of
others to confirm that dereferencing does the right thing, regardless of
how the iterator was found, and that iteration works correctly from each
return from find.

fd03357c25 Make the moved-from SmallPtrSet be a valid, empty, small-state object.
Enhance the tests to actually require moves in C++11 mode, in addition
to testing the moved-from state. Further enhance the tests to cover
copy-assignment into a moved-from object and moving a large-state
object. (Note that we can't really test small-state vs. large-state as
that isn't an observable property of the API really.) This should finish
addressing review on r195239.

46198164b3 Give SmallPtrSet move semantics when we have R-value references.
Somehow, this ADT got missed which is moderately terrifying considering
the efficiency of move for it.

The code to implement move semantics for it is pretty horrible
currently but was written to reasonably closely match the rest of the
code. Unittests that cover both copying and moving (at a basic level)
added.

2945a32ffd SmallPtrSet: Provide a more efficient implementation of swap than the default triple-copy std::swap.
This currently assumes that both sets have the same SmallSize to keep the implementation simple,
a limitation that can be lifted if someone cares.
