Object of class `Command` contains various properties of a command to
execute, but output file was missed from them. This change adds this
property. It is required for reporting consumed time and memory implemented
in D78903 and may be used in other cases too.

specified at Command creation, rather than as part of the Tool.
This resolves the hack I just added to allow Darwin toolchain to vary
its level of support based on `-mlinker-version=`.
The change preserves the _current_ settings for response-file support.
Some tools look likely to be declaring that they don't support
response files in error, however I kept them as-is in order for this
change to be a simple refactoring.

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.

In these combinations, link a DLL as usual, but pass -Bstatic instead
of -Bdynamic to indicate prefering static libraries.

This commit fixes a bug where clang/llvm doesn't emit an unwind table
for a function when it is marked noexcept. Without this patch, the
following code terminates with an uncaught exception on ARM64:
int foo1() noexcept {
try {
throw 0;
} catch (int i) {
return 0;
}
return 1;
}
int main() {
return foo1();
}

Projects that want to statically link their own C++ standard library currently
need to pass -nostdlib or -nodefaultlibs, which also disables linking of the
builtins library, -lm, and so on. Alternatively, they could use `clang` instead
of `clang++`, but that already disables implicit addition of -lm on some
toolchains.
Add a dedicated flag -nostdlib++ that disables just linking of libc++ /
libstdc++. This is analogous to -nostdinc++.

This changes CrossWindows to look for -nostdinc instead of -nostdlibinc.
In addition, fixes a bug where -isystem-after options would be dropped
when called with -nostdinc.

When building with libc++ don't bother with injecting the libstdc++
search paths into the linker search path. This will make it easier to
switch between ld and lld.

crtbegin is not really a proper windows support thing. This was
duplicated when the toolchain was initially built. If the injection of
crtbegin is needed, it can be done via the `/include` directive.
Furthermore, since `-fPIC` doesnt make sense on PE/COFF, crtbegin and
crtbeginS dont really need to be different.

Summary:
(This is a move-only refactoring patch. There are no functionality changes.)
This patch splits apart the Clang driver's tool and toolchain implementation
files. Each target platform toolchain is moved to its own file, along with the
closest-related tools. Each target platform toolchain has separate headers and
implementation files, so the hierarchy of classes is unchanged.
There are some remaining shared free functions, mostly from Tools.cpp. Several
of these move to their own architecture-specific files, similar to r296056. Some
of them are only used by a single target platform; since the tools and
toolchains are now together, some helpers now live in a platform-specific file.
The balance are helpers related to manipulating argument lists, so they are now
in a new file pair, CommonArgs.h and .cpp.
I've tried to cluster the code logically, which is fairly straightforward for
most of the target platforms and shared architectures. I think I've made
reasonable choices for these, as well as the various shared helpers; but of
course, I'm happy to hear feedback in the review.
There are some particular things I don't like about this patch, but haven't been
able to find a better overall solution. The first is the proliferation of files:
there are several files that are tiny because the toolchain is not very
different from its base (usually the Gnu tools/toolchain). I think this is
mostly a reflection of the true complexity, though, so it may not be "fixable"
in any reasonable sense. The second thing I don't like are the includes like
"../Something.h". I've avoided this largely by clustering into the current file
structure. However, a few of these includes remain, and in those cases it
doesn't make sense to me to sink an existing file any deeper.
