Make llvm::StringRef to std::string conversions explicit.

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.

[DeclCXX] Remove unknown external linkage specifications

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

With this patch we now treat lang_cxx, lang_cxx_11 and lang_cxx_14 the
same way in the switch in VisitLinkageSpecDecl.

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.

[Tooling] [1/1] Refactor FrontendActionFactory::create() to return std::unique_ptr<>

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.
