reduced test case of ICE when compiling with -O2
-fplugin-arg-dragonegg-enable-gcc-optzns -ftree-vectorize

Both llvm/dragonegg 3.0 and svn ICE the FSF gcc 4.6svn compiler when compiling
the iniprs subroutine from parser.f of xplor-nih. The attached reduced test
case reproduces this issue seen with -O2
-fplugin-arg-dragonegg-enable-gcc-optzns -ftree-vectorize.
