Fix Clang 9.0.0 warnings

Run ARM64 tests on REAL HARDWARE 🎉

clang-tidy9.0.0 added a new check: bugprone-branch-clone
(https://releases.llvm.org/9.0.0/tools/clang/tools/extra/docs/ReleaseNotes.html)
This doesn't like both branches of an if are the same.
This lead to a warning in rainbow, as where the maximum of two values (which
are always the same) is computed in a macro.
I don't always agree with this warning, but here I think it's worth to
remove the macro.

clang-tidy9.0.0 added a new check: bugprone-branch-clone
(https://releases.llvm.org/9.0.0/tools/clang/tools/extra/docs/ReleaseNotes.html)
This doesn't like both branches of an if are the same.
In this case I don't think there is any reason to do this, so I've removed it.

clang9.0.0 (https://releases.llvm.org/9.0.0/tools/clang/docs/ReleaseNotes.html)
adds a new satic analyzer: security.insecureAPI.DeprecatedOrUnsafeBufferHandling
which throws warnings if you use "unsafe" buffer handling functions which
includes memset and memcpy.
We have memset and mempy all over the place, so I think it's best to ignore this warning.
All the occurences that I looked at seemed perfectly "safe" to me.

Make sure the emulated jobs upload their test results properly

* Copied qTESLA-p-I round2 (2019-08-19) code

* Code compiles, NIST-KAT works

* Included detached signature API

* Generated testvectors

* Fixed name in api.h

* code style

* Fixed error in Makefile

* Passing pytest

* Fixing types (uint8_t bytes and size_t indices)

* Replaced SHAKE with SHAKE128 where necessary

* Fixed bug: (signed) integer overflow

* Added qTESLA-p-III

* Code is now independent of machine endianness

* repaired Microsoft makefile

Fix kyber-90s warning if size_t is not 32 bits

Update Kyber-90s to use aes256_ecb instead of local AES implementation

It seems wise to include _some_ form of guidance on what we know about
problems with certain (versions of) implementations.

[ci skip]

Fix and re-add Rainbow

Add 90s variants of Kyber

Fix CRYPTO_ALGNAME

Add duplicate consistency files

Fixed sampler bug (update to new upstream Falcon code 2019-09-18).

* Ignore pointless clang-tidy warning.

It wants you to write type suffixes for integers using uppercase. Let's
just disable this warning.

* Clean up bugprone-narrowing-conversion

Check and fix consistency of scheme names

Fix incremental sha512

* Integrate Kyber-AVX2 into PQClean

* Fix types and formatting in Kyber

* Workaround a valgrind crash

* Remove comment in shuffle.s

* Remove some extraneous truncations

* fixup! Fix types and formatting in Kyber

* Add support for specifying architecture and feature limits

* cpuinfo not supported on ppc

* Detect 32-bit python interpreter on 64-bit CPU

* Fix bugs in isolated tests

* Also support restricting operating system

* Enable valgrind exit errorcode

It seems we were not doing anything with the valgrind results... D:

* Use --exit-on-first-error if available

* Revert "Merge pull request #182 from PQClean/rainbow"

This reverts commit 8a008417fe988b48c8acc4aefc9c299a4d3c1645, reversing
changes made to d4b612fe9a.

update LEDA to v2.1
