This is a follow-up of e92d2b80c6c9 ("[Driver] Detect libstdc++ include
paths for native gcc (-m32 and -m64) on Debian i386") for the Debian Hurd
case, which has the same multiarch name reduction from i686 to i386.
i386-linux-gnu is actually Linux-only, so this moves the code of that commit
to Linux.cpp, and adds the same to Hurd.cpp

Summary:
The Android NDK's clang driver is used with an Android -target setting,
and the driver automatically finds the Android sysroot at a path
relative to the driver. The sysroot has the libc++ headers in it.
Remove Hurd::computeSysRoot as it is equivalent to the new
ToolChain::computeSysRoot method.
Fixes PR46213.

A two-stage ThinLTO build previously failed the clang/test/Driver/hurd.c test because of a static_cast in "tools::gnutools::Linker::ConstructJob()" which wrongly converted an instance of "clang::driver::toolchains::Hurd" into that of "clang::driver::toolchains::Linux". ThinLTO would later devirtualize the "ToolChain.getDynamicLinker(Args)" call and use "Linux::getDynamicLinker()" instead, causing the test to generate a wrong "-dynamic-linker" linker flag (/lib/ld-linux.so.2 instead of /lib/ld.so)
Fixes PR45061.

Linux' current addLibCxxIncludePaths and addLibStdCxxIncludePaths
are actually almost non-Linux-specific at all, and can be reused
almost as such for all gcc toolchains. Only keep
Android/Freescale/Cray hacks in Linux's version.

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.

This adds Hurd toolchain support to Clang's driver in addition
to handling translating the triple from Hurd-compatible form to
the actual triple registered in LLVM.
(Phabricator was stripping the empty files from the patch so I
manually created them)
