I 'mucked about' with this package locally and imported upstream version
22.1.7. It's very likely I didn't do it as expected by this package, but
I made it work. That resulted in 1 less failing test:

LLVM_SPIRV :: llvm-intrinsics/constrained-arithmetic.ll

But I noticed that upstream had various backported commits in their
llvm_release_220 branch *after* the 22.1.7 tag, so I grabbed that and added
that to ``debian/patches``. One of them was a(n officially) backported patch
of upstream PR 3568, so I updated/replaced ``3568.patch`` with that one.

When I build that, the build succeeded \o/.
Lintian did report an error wrt symbols:
  E: libllvmspirvlib22.1: symbols-file-contains-current-version-with-debian-revision on symbol \
  _ZN4llvm16getSpecConstInfoERSiRKN5SPIRV14TranslatorOptsERSt6vectorINS_15SpecConstInfoTyESaIS6_EE at Base \
  and 13 others (libLLVMSPIRVLib.so.22.1) [symbols]

I'll attach all the patches I've used; I'm sure one of the maintainers
can build a proper package from that ;-)

Cheers,
  Diederik
