pb05 benchmarks for llvm 3.3/3.4svn

Below are the results for the Polyhedron 2005 benchmarks compiled with the llvm/compiler-rt/dragonegg 3.3
release and 3.4svn against FSF gcc 4.8.2. The *-stock-de runs omit the -fplugin-arg-dragonegg-enable-gcc-optzns
flag and the *-de-optnz runs include it. There seems to be little improvement between llvm 3.3 and 3.4 in the
stock case which relies entirely on llvm for vectorization.
Duncan, has dragonegg been updated to enable the same llvm vectorization options as clang for the 3.4 release?
If not, we may be leaving some potential vectorization improvements on the table here.
