Before r314561, I could build LibreOffice with the NewGVN. After r314561, clang
would crash building the firebird module. After r314622, the build fails during
the basic Unit Testing phase. 


Steps to reproduce:
1. $ git clone git://anongit.freedesktop.org/libreoffice/core
2. $ apt-get build-dep libreoffice 
3. create file autogen.input with CC=clang and CXX=clang++
4. ./autogen.sh && make ENVCFLAGS="-mllvm -enable-newgvn" ENVCFLAGSCXX="-mllvm
-enable-newgvn"


r314561 firebird crash:
