This patch provides more information to the
`PPCallbacks::InclusionDirective()` hook. We now always pass the
suggested module, regardless of whether it was actually imported or not.
The extra `bool ModuleImported` parameter then denotes whether the
header `#include` will be automatically translated into import the the
module.
The main change is in `clang/lib/Lex/PPDirectives.cpp`, where we take
care to not modify `SuggestedModule` after it's been populated by
`LookupHeaderIncludeOrImport()`. We now exclusively use the `SM`
(`ModuleToImport`) variable instead, which has been equivalent to
`SuggestedModule` until now. This allows us to use the original
non-modified `SuggestedModule` for the callback itself.
(This patch turns out to be necessary for
https://github.com/apple/llvm-project/pull/8011).
This patch replaces uses of StringRef::{starts,ends}with with
StringRef::{starts,ends}_with for consistency with
std::{string,string_view}::{starts,ends}_with in C++20.
I'm planning to deprecate and eventually remove
StringRef::{starts,ends}with.
The needed tweaks are mostly trivial, the one nasty bit is Clang's usage
of OptionalStorage. To keep this working old Optional stays around as
clang::CustomizableOptional, with the default Storage removed.
Optional<File/DirectoryEntryRef> is replaced with a typedef.
I tested this with GCC 7.5, the oldest supported GCC I had around.

This reverts commit 8f0df9f3bbc6d7f3d5cbfd955c5ee4404c53a75d.
The Optional*RefDegradesTo*EntryPtr types want to keep the same size as
the underlying type, which std::optional doesn't guarantee. For use with
llvm::Optional, they define their own storage class, and there is no way
to do that in std::optional.
On top of that, that commit broke builds with older GCCs, where
std::optional was not trivially copyable (static_assert in the clang
sources was failing).
llvm::sort is beneficial even when we use the iterator-based overload,
since it can optionally shuffle the elements (to detect
non-determinism). However llvm::sort is not usable everywhere, for
example, in compiler-rt.

This patch changes type of the `File` parameter in `PPCallbacks::InclusionDirective()` from `const FileEntry *` to `Optional<FileEntryRef>`.
With the API change in place, this patch then removes some uses of the deprecated `FileEntry::getName()` (e.g. in `DependencyGraph.cpp` and `ModuleDependencyCollector.cpp`).

LLVM style puts both gtest and gmock to the end of the include list.
But llvm-include-order-check was only moving gtest headers to the end, resulting
in a false tidy-warning.

This is how it should've been and brings it more in line with
std::string_view. There should be no functional change here.
This is mostly mechanical from a custom clang-tidy check, with a lot of
manual fixups. It uncovers a lot of minor inefficiencies.
This doesn't actually modify StringRef yet, I'll do that in a follow-up.
Now that we've moved to C++14, we no longer need the llvm::make_unique
implementation from STLExtras.h. This patch is a mechanical replacement
of (hopefully) all the llvm::make_unique instances across the monorepo.

Summary:
Change the namespace for llvm checkers from 'llvm' to
'llvm_check', and modify add_new_check.py and rename_check.py to
support the new namespace. Checker, file, and directory names remain
unchanged.
Used new version of rename_check.py to make the change in existing
llvm checkers, but had to fix LLVMTidyModule.cpp and
LLVMModuleTest.cpp by hand.
The changes made by rename_check.py are idempotent, so if accidentally
run multiple times, it won't do anything.

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.

The include order check would get notified of all include
directives in a depth-first manner. This created the
possibility of an include directive from a header file
interfering with the sort order of a set of two distinct
blocks from the top level cpp file, if that include directive
was on just the right line.
With this patch we bucket the include directives by the file
in which they appear in and process one bucket at a time,
so that directives from different files do not get mixed
together into the same list.

There are still a couple of rough edges in here but it is working fine
on LLVM and generates the same results as sort_includes.py if there are
no blank lines involved.

The state of this check now seems to be enough to enable it by default to gather
