* //third_party/{abseil_cpp, grpc}: fix linker problem by passing the
C++ standard to use explicitly. nixpkgs upstream stopped passing this
to abseil between bumps and the way this problem manifests itself is
linker errors, because… C++, I suppose.

The point where this broke is likely when llvmPackages_11.stdenv started
respecting stdenv.hostPlatform.linker and thus using GNU binutils'
ld.bfd for linking. That linker can't deal with clang's C++ ABI.
To fix this we introduce a modified version of llvmPackages_11.stdenv
which uses llvmPackages_11.bintools for linking purposes (I also aim to
upstream this in some form, but am not sure about the details atm, so
we'll just do this in the tvl overlay for now). This is the precondition
for getting our C++ packages in //third_party to work
again. Additionally the following fixes were necessary:
* abseil-cpp needed to be updated (by overriding the version from
nixpkgs for now, since I can't update the subtree on my own) to
fulfill grpc's requirements (grpc 1.41.0 needs abseil-cpp LTS
20210324).
* gtest needs a patch from nixpkgs which fixes the path to its include
directory for CMake.
* We need to build re2 with clang as well, otherwise linking will fail.
Fixes b/132.

* This was mostly for //third_party/nix and its dependencies which now
have been set to use llvmPackages_11 manually.
* For //users/grfn/achilles we also manually select the newer LLVM version.
* //tools/cheddar doesn't seem to need llvm anymore.
* //third_party/buzz also compiles with clang 7.1.0
* replace clang-tools everywhere with new attribute clang-tools_11
For the future we may want to have something similar again, but it may
not be necessary to invest too much time into it: nixpkgs is set to
upgrade their default llvmPackages to LLVM 11 as well at some point in
the near future.

... notably, this includes Abseil's own StatusOr type, which
conflicted with our implementation (that was taken from TensorFlow).

Additionally, add tests for the macros. A future CL will enable the tests in CI.

This didn't work previously ... but now it does. I think setting the
standard explicitly is what did the trick, but it's slightly unclear
to me why.
Either way this means that Abseil is no longer constantly getting
recompiled when building Nix, which is nice.
