After commit r294897, LibreOffice cannot be built with the NewGVN. 

Steps to reproduce:
1. $ git clone git://anongit.freedesktop.org/libreoffice/core
2. $ apt-get build-dep libreoffice ( also lo_usefull Shell Script if missing
dep)
3. Remove ccache if it's installed ( ccache generates warning w/ clang)
4. create file autogen.input with CC=clang and CXX=clang++
5 ./autogen.sh && make ENVCFLAGS="-mllvm -enable-newgvn" ENVCFLAGSCXX="-mllvm
-enable-newgvn"

after r294897
build fails with hwpfilter_test_hwpfilter.test' unit test failed

after r296000 
LibreOffice will fail with the following error
