valgrind apitrace mesa-a3ae5dc7dd5c2f8893f86a920247e690e550ebd4

Steps to reproduce:
# good commit: 98d2498404ba69a3efc1c765b1a1885d151181ed
# bad commit:
git checkout a3ae5dc7dd5c2f8893f86a920247e690e550ebd4
NOCONFIGURE=1 ./autogen.sh
./configure --prefix=/tmp/mesa-root --with-gallium-drivers=swrast
--with-dri-drivers=i965 --with-llvm-shared-libs --enable-gallium-llvm
--enable-shared-glapi --enable-dri --enable-glx --enable-texture-float
make install

Run with:
LIBGL_DEBUG=verbose \
LD_LIBRARY_PATH=/tmp/mesa-root/lib \
LIBGL_DRIVERS_PATH=/tmp/mesa-root/lib/dri \
LIBGL_ALWAYS_SOFTWARE=1 \
valgrind glretrace /tmp/java.trace

This is tested with LLVM 3.3. The two conditional jump warnings are also
present in the "good" commit, everything thereafter is new (starting from
"Invalid write").
