Several of these failures are quite similar backend code generator problems.
More details from one of the failures:

I've built it locally and saved the reproducer (attached).
Can be tested on amd64 too if you have ports-clang installed and modify
the script from /usr/bin/c++ to /usr/local/bin/clang++.
Does anyone have clang on another OS or a newer version handy that they
could test with? (I've tried updating the ports version but have thus
far failed to merge the patches to get something which builds).
