When testing clang that has been compiled with `-DDEFAULT_SYSROOT` set to some path,
some tests would fail. Override sysroot to be empty string for the tests to succeed
when clang is configured with `DEFAULT_SYSROOT`.

Summary:
Setting CLANG_LINK_CLANG_DYLIB=ON causes clang tools to link against
libclang_shared.so instead of the individual component libraries.

When more than one multilib flag matches, try to select the best
possible match based on priority. When two different multilibs with
the same same priority match, we still throw an error matching the
existing behavior.

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.

Add support for distinguishing plain Gentoo distribution, and a unit
test for it. This is going to be used to introduce distro-specific
customizations in the driver code; most notably, it is going to be used
to disable -faddrsig.

This patch moves the virtual file system form clang to llvm so it can be
used by more projects.
Concretely the patch:
- Moves VirtualFileSystem.{h|cpp} from clang/Basic to llvm/Support.
- Moves the corresponding unit test from clang to llvm.
- Moves the vfs namespace from clang::vfs to llvm::vfs.
- Formats the lines affected by this change, mostly this is the result of
the added llvm namespace.

requested name
Summary:
InMemoryFileSystem::status behaves differently than
RealFileSystem::status. The Name contained in the Status returned by
RealFileSystem::status will be the path as requested by the caller,
whereas InMemoryFileSystem::status returns the normalized path.
For example, when requested the status for "../src/first.h",
RealFileSystem returns a Status with "../src/first.h" as the Name.
InMemoryFileSystem returns "/absolute/path/to/src/first.h".
The reason for this change is that I want to make a unit test in the
clangd testsuite (where we use an InMemoryFileSystem) to reproduce a
bug I get with the clangd program (where a RealFileSystem is used).
This difference in behavior "hides" the bug in the unit test version.
An indirect impact of this change is that a -Wnonportable-include-path
warning is now emitted in test PCH/case-insensitive-include.c. This is
because the real path of the included file (with the wrong case) was not
available previously, whereas it is now.

In general, I guess it's good if InMemoryFileSystem works as much as
possible like RealFileSystem.
Doing so made the FileEntry::RealPathName value (assigned in
FileManager::getFile) wrong when using the InMemoryFileSystem. That's
because it assumes that vfs::File::getName will always return the real
path. I changed to to use FileSystem::getRealPath instead.

LLVM_ON_WIN32 is set exactly with MSVC and MinGW (but not Cygwin) in
HandleLLVMOptions.cmake, which is where _WIN32 defined too. Just use the
default macro instead of a reinvented one.
See thread "Replacing LLVM_ON_WIN32 with just _WIN32" on llvm-dev and cfe-dev.

We currently use target_link_libraries without an explicit scope
specifier (INTERFACE, PRIVATE or PUBLIC) when linking executables.
Dependencies added in this way apply to both the target and its
dependencies, i.e. they become part of the executable's link interface
and are transitive.
Transitive dependencies generally don't make sense for executables,
since you wouldn't normally be linking against an executable. This also
causes issues for generating install export files when using
LLVM_DISTRIBUTION_COMPONENTS. For example, clang has a lot of LLVM
library dependencies, which are currently added as interface
dependencies. If clang is in the distribution components but the LLVM
libraries it depends on aren't (which is a perfectly legitimate use case
if the LLVM libraries are being built static and there are therefore no
run-time dependencies on them), CMake will complain about the LLVM
libraries not being in export set when attempting to generate the
install export file for clang. This is reasonable behavior on CMake's
part, and the right thing is for LLVM's build system to explicitly use
PRIVATE dependencies for executables.
Unfortunately, CMake doesn't allow you to mix and match the keyword and
non-keyword target_link_libraries signatures for a single target; i.e.,
if a single call to target_link_libraries for a particular target uses
one of the INTERFACE, PRIVATE, or PUBLIC keywords, all other calls must
also be updated to use those keywords. This means we must do this change
in a single shot. I also fully expect to have missed some instances; I
tested by enabling all the projects in the monorepo (except dragonegg),
and configuring both with and without shared libraries, on both Darwin
and Linux, but I'm planning to rely on the buildbots for other
configurations (since it should be pretty easy to fix those).
Even after this change, we still have a lot of target_link_libraries
calls that don't specify a scope keyword, mostly for shared libraries.
I'm thinking about addressing those in a follow-up, but that's a
separate change IMO.

there's an error somewhere.
This is a more principled version of r303756. That change was both very
brittle about the state of the Diags object going into the driver and
also broke tooling in funny ways.
In particular it prevented tools from capturing diagnostics properly and
made the compilation database logic fail to provide arguments to the
tool, falling back to scanning directories for JSON files.

This is recommit of r302775, reverted in r302777 due to a fail in
clang-tidy. Original mesage is below.
Now if clang driver is given wrong arguments, in some cases it
continues execution and returns zero code. This change fixes this
behavior.
The fix revealed some errors in clang test set.
File test/Driver/gfortran.f90 added in r118203 checks forwarding
gfortran flags to GCC. Now driver reports error on this file, because
the option -working-directory implemented in clang differs from the
option with the same name implemented in gfortran, in clang the option
requires argument, in gfortran does not.
In the file test/Driver/arm-darwin-builtin.c clang is called with
options -fbuiltin-strcat and -fbuiltin-strcpy. These option were removed
in r191435 and now clang reports error on this test.
File arm-default-build-attributes.s uses option -verify, which is not
supported by driver, it is cc1 option.
Similarly, the file split-debug.h uses options -fmodules-embed-all-files
and -fmodule-format=obj, which are not supported by driver.
Other revealed errors are mainly mistypes.

Add a set of unit tests for the distro detection code. The tests use an
in-memory virtual filesystems resembling release files for various
distributions supported. All release files are provided (not only the
ones directly used) in order to guarantee that one of the rules will not
mistakenly recognize the distribution incorrectly due to the additional
files (e.g. Ubuntu as Debian).

Currently, if --driver-mode is not passed at all, it will default
to GCC style driver. This is never an issue for clang because
it manually constructs a --driver-mode option and passes it.
However, we should still try to do as good as we can even if no
--driver-mode is passed. LibTooling, for example, does not pass
a --driver-mode option and while it could, it seems like we should
still fallback to the best possible default we can.
This is one of two steps necessary to get clang-tidy working on Windows.

If the user configured clang with a custom GCC toolchain that will take precedence on what the ToolChainTest.cpp expects to evaluate.
This is fixed here by passing --gcc-toolchain= to the driver, in order to override any user defined GCC toolchain.

a missing include from CLog.h.
CLog.h referenced most of the core libclang types but never directly
included Index.h that provides them. Previously it got lucky and other
headers were always included first but with the sorting it ended up
first in one case and stopped compiling. Adding the Index.h include
fixes it right up.

It also provides a better approximation for the flags '-print-multi-directory'

This reverts r201203 (i.e. re-applying r201202 with small fixes in
