In build_symbolizer.sh we can safely remove the -eu argument from the shebang (which is an unportable construct), as the scripts sets **-e** and **-u** already.

In this mode libc++ headers end up in two directories:
* include/<triple>/c++/v1 for the site config header
* include/c++/v1 for everything else
Also switch from -I to -isystem.

Ensure that libSupport does not carry any static global initializer.
libSupport can be embedded in use cases where we don't want to load all
cl::opt unless we want to parse the command line.
ManagedStatic can be used to enable lazy-initialization of globals.
The -Werror=global-constructors is only added on platform that have
support for the flag and for which std::mutex does not have a global
destructor. This is ensured by having CMake trying to compile a file
with a global mutex before adding the flag to libSupport.
Summary: https://reviews.llvm.org/D66620 is accepted but was based on the multi-repo setup, so I was not able to `arc patch` it. Resubmit the diff under monorepo

(sanitizer-x86_64-linux) until I can triage the issue properly. The
build has been broken due to the symbolizer build checks failing.
As the symbolizer build script relies on the old svn repo layout, it may
take a little while longer to find the responsible patch for the
breakage. This may be a completely valid fix, but I will need to confirm
it. For now, it unbreaks the build.
Tracking data:

For the authors, no action needed (yet). Will follow up when I can
identify the cause.

llvm-ar is a crunchgen-style executable dispatching to dlltool,ranlib,lib,ar based on argv[0].
In our content-addressable storage, readlink -f resolves paths to some
digest and thus lost the original "llvm-ar" filename.
Replace it with a custom path resolution to fix the problem.

Disabling threads makes <atomic> unusable, but this is needed by LLVM
libraries that are dependencies of the symbolizer.
