Don't call raw_string_ostream::flush(), which is essentially a no-op.
As specified in the docs, raw_string_ostream is always unbuffered.

This patch deprecates `module.map` in favor of `module.modulemap`, which
has been the preferred form since 2014. The eventual goal is to remove
support for `module.map` to reduce the number of stats Clang needs to do
while searching for module map files.
This patch touches a lot of files, but the majority of them are just
renaming tests or references to the file in comments or documentation.
The relevant files are:
* lib/Lex/HeaderSearch.cpp
* include/clang/Basic/DiagnosticGroups.td
* include/clang/Basic/DiagnosticLexKinds.td
This is a big refactor of the clang driver's option handling to use
the Visibility flags introduced in https://reviews.llvm.org/D157149.
There are a few distinct parts, but they can't really be split into
separate commits and still be made to compile.
1. We split out some of the flags in ClangFlags to ClangVisibility.
Note that this does not include any subtractive flags.
2. We update the Flag definitions and OptIn/OptOut constructs in
Options.td by hand.
3. We introduce and use a script, update_options_td_flags, to ease
migration of flag definitions in Options.td, and we run that on
Options.td. I intend to remove this later, but I'm committing it so
that downstream forks can use the script to simplify merging.
4. We update calls to OptTable in the clang driver, cc1as, flang, and
clangd to use the visibility APIs instead of Include/Exclude flags.
5. We deprecate the Include/Exclude APIs and add a release note.
*if you are running into conflicts with this change:*
Note that https://reviews.llvm.org/D157150 may also be the culprit and
if so it should be handled first.
The script in `clang/utils/update_options_td_flags.py` can help. Take
the downstream side of all conflicts and then run the following:
```
% cd clang/include/clang/Driver
% ../../../utils/update_options_td_flags.py Options.td > Options.td.new
% mv Options.td.new Options.td
```
This will hopefully be sufficient, please take a look at the diff.

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.
Partial revert of r372681 "Support for DWARF-5 C++ language tags".
The change introduced new external linkage languages ("C++11" and
"C++14") which not supported in C++.
It also changed the definition of the existing enum to use the DWARF
constants. The problem is that "LinkageSpecDeclBits.Language" (the field
that reserves this enum) is actually defined as 3 bits length
(bitfield), which cannot contain the new DWARF constants. Defining the
enum as integer literals is more appropriate for maintaining valid
values.

In r372681 lang_cxx_11 and lang_cxx_14 were added to LanguageIDs
but they were not handled in the switch in VisitLinkageSpecDecl in
Modularize.cpp so at clang 8 complained with
/data/repo/master/clang-tools-extra/modularize/Modularize.cpp:583:13: error: enumeration values 'lang_cxx_11' and 'lang_cxx_14' not handled in switch [-Werror,-Wswitch]
switch (D->getLanguage()) {
^
1 error generated.
With this patch we now treat lang_cxx, lang_cxx_11 and lang_cxx_14 the
same way in the switch in VisitLinkageSpecDecl.

Summary:
This significantly reduces the time required to run clangd tests, by
~10%.
Should also have an effect on other tests that run command-line parsing
multiple times inside a single invocation.

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.

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.

also return a non-zero exit code. Fixed tests accordingly.

Summary:
I'm not sure whether there are any principal reasons why it returns raw owning pointer,
or it is just a old code that was not updated post-C++11.
I'm not too sure what testing i should do, because `check-all` is not error clean here for some reason,
but it does not //appear// asif those failures are related to these changes.
This is Clang-tools-extra part.
Clang part is D43779.

to determine files that have comnpilation or dependency problems.
A new -display-file-lists option use this to display lists of good files
(no compile errors), problem files, and a combined list with
problem files preceded by a '#'. The problem files list can be
used in the module map generation assistant mode to exclude
problem files. The combined files list can be used during module
map development. See added docs.
