FAIL: gcc.dg/vect/vect-outer-5.c (internal compiler error)

Compiler configured with:

Configured with: $SOURCE/gcc/configure --target=arm-none-eabi
--prefix=$SOURCE/build/install --with-gmp=$SOURCE/build/host-tools
--with-mpfr=$SOURCE/build/host-tools --with-mpc=$SOURCE/build/host-tools
--with-pkgversion=unknown --disable-shared --disable-nls --disable-threads
--disable-tls --enable-checking=yes --enable-languages=c,c++,fortran
--with-newlib --with-fpu=neon-fp16 --with-float=hard --with-arch=armv7-a

ICE triggered for me with the command:
arm-none-eabi-gcc -fno-diagnostics-show-caret -ffast-math -ftree-vectorize
-fno-vect-cost-model -fno-common -O2 -fdump-tree-vect-details -S vect-outer-5.i

caused by r196770.

I believe Richard already has a patch queued to fix this
