What is the output of "/usr/bin/clang++ -v" ?

Right, that seems okay enough. Any other information you can give to
help reproduce this issue would be nice. For example, do you have any
special stuff in src.conf or make.conf? Do you have more than one
"clang++" in your PATH, maybe an old port version?
So I've started from scratch:
1. rm -Rf /usr/src/*
2. portinstall subversion-freebsd
3. checkout fresh sources
4. disabled clang debugging in/src/lib/clang/clang.build.mk for speed
measuring
5. rebuild and reinstall world & kernel via GCC (without src.conf)
6. after new world is alive rebuild and reinstall world & kernel via
CLANG (with src.conf, and no problem with this part)
7. Another buildworld try and here's the bug again (output seems to be
different only because of disables debugging):

Interesting, because it seems that only clang builded by clang has a
problem to build clang, while clang builded by gcc has not ;)
I've never had clang port installed so problem must be somewhere elsewhere.

and the resulting APFloat.ii, APFloat.s (if clang manages to produce
it)?
APFloat.s was created and it's empty.
Here you can grab the other: http://ncpnc.obsysa.net/tmp/APFloat.ii.bz2
