Fix the confusing naming of `CompilerInstance::ModuleManager`. This is
actually an instance of `ASTReader`, which contains an instance of
`ModuleManager`. I have to assume there was a point in the past where
they were just one class, but it's been pretty confusing for a while. I
think it's time to fix it.
The new name is `TheASTReader`; the annoying `The` prefix is so that we
don't shadow the `ASTReader` class. I tried out `ASTRdr` but that
seemed less clear, and this choice matches `ThePCHContainerOperations`
just a couple of declarations below.
Also rename `CompilerInstance::getModuleManager` and
`CompilerInstance::createModuleManager` to `*ASTReader`, making some
cases of `getModuleManager().getModuleManager()` a little more clear.

Remove some cognitive load by renaming clang/Serialization/Module.h to
clang/Serialization/ModuleFile.h, since it declares the ModuleFile
class. This also makes editing a bit easier, since the basename of the
file no long conflicts with clang/Basic/Module.h, which declares the
Module class. Also move lib/Serialization/Module.cpp to
lib/Serialization/ModuleFile.cpp.

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.

This patch is a prerequisite for using LangStandard from Driver in
https://reviews.llvm.org/D64793.
It moves LangStandard* and InputKind::Language to Basic. It is mostly
mechanical, with only a few changes of note:
- enum Language has been changed into enum class Language : uint8_t to
avoid a clash between OpenCL in enum Language and OpenCL in enum
LangFeatures and not to increase the size of class InputKind.
- Now that getLangStandardForName, which is currently unused, also checks
both canonical and alias names, I've introduced a helper getLangKind
which factors out a code pattern already used 3 times.
The patch has been tested on x86_64-pc-solaris2.11, sparcv9-sun-solaris2.11,
and x86_64-pc-linux-gnu.
There's a companion patch for lldb which uses LangStandard.h
(https://reviews.llvm.org/D65717).
While polly includes isl which in turn uses InputKind::C, that part of the
code isn't even built inside the llvm tree. I've posted a patch to allow
for both InputKind::C and Language::C upstream
(https://groups.google.com/forum/#!topic/isl-development/6oEvNWOSQFE).

The bitstream reader handles errors poorly. This has two effects:
* Bugs in file handling (especially modules) manifest as an "unexpected end of
file" crash
* Users of clang as a library end up aborting because the code unconditionally
calls `report_fatal_error`
The bitstream reader should be more resilient and return Expected / Error as
soon as an error is encountered, not way late like it does now. This patch
starts doing so and adopting the error handling where I think it makes sense.
There's plenty more to do: this patch propagates errors to be minimally useful,
and follow-ups will propagate them further and improve diagnostics.

Change MemoryBufferCache to InMemoryModuleCache, moving it from Basic to
Serialization. Another patch will start using it to manage module build
more explicitly, but this is split out because it's mostly mechanical.
Because of the move to Serialization we can no longer abuse the
Preprocessor to forward it to the ASTReader. Besides the rename and
file move, that means Preprocessor::Preprocessor has one fewer parameter
and ASTReader::ASTReader has one more.

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.

modules to preprocessing of nested .pcm files.
Making those module files available results in loading more .pcm files than
necessary, and potentially in misbehavior if a module makes itself visible
during its own compilation (as parts of that module that have not yet been
processed would then become visible).

If specified, when preprocessing, the contents of imported .pcm files will be
included in preprocessed output. The resulting preprocessed file can then be
compiled standalone without the module sources or .pcm files.

No-one was using this, and it's not meaningful in general -- FrontendActions
can be run on inputs that don't have a corresponding source file. The current
frontend input can be obtained by asking the FrontendAction if any future
action actually needs it.

To support this, an optional marker "#pragma clang module contents" is
recognized in module map files, and the rest of the module map file from that
point onwards is treated as the source of the module. Preprocessing a module
map produces the input module followed by the marker and then the preprocessed
contents of the module.
Ignoring line markers, a preprocessed module might look like this:
module A {
header "a.h"
}
#pragma clang module contents
#pragma clang module begin A
// ... a.h ...
#pragma clang module end
The preprocessed output generates line markers, which are not accepted by the
module map parser, so -x c++-module-map-cpp-output should be used to compile
such outputs.
A couple of major parts do not work yet:
1) The files that are listed in the module map must exist on disk, in order to
build the on-disk header -> module lookup table in the PCM file. To fix
this, we need the preprocessed output to track the file size and other stat
information we might use to build the lookup table.
2) Declaration ownership semantics don't work properly yet, since mapping from
a source location to a module relies on mapping from FileIDs to modules,
which we can't do if module transitions can occur in the middle of a file.

This changes the CompilerInstance::createOutputFile function to return
a std::unique_ptr<llvm::raw_ostream>, rather than an llvm::raw_ostream
implicitly owned by the CompilerInstance. This in most cases required that
I move ownership of the output stream to the relevant ASTConsumer.
The motivation for this change is to allow BackendConsumer to be a client
of interfaces such as D20268 which take ownership of the output stream.

(after fixing a bug in MultiplexConsumer I noticed the ownership of the
nested consumers was implemented with raw pointers - so this fixes
that... and follows the source back to its origin pushing unique_ptr
ownership up through there too)

The rewrite facility's footprint is small so it's not worth going to these
lengths to support disabling at configure time, particularly since key compiler
features now depend on it.
Meanwhile the Objective-C rewriters have been moved under the
ENABLE_CLANG_ARCMT umbrella for now as they're comparatively heavy and still
potentially worth excluding from lightweight builds.
Tests are now passing with any combination of feature flags. The flags
historically haven't been tested by LLVM's build servers so caveat emptor.
