preprocessed test case

Several files in gsoc2010-fftw-neon ICE gcc-4.4 in change_address_1, this is
the preprocessed code for the first one.

The ICE doesn't occur with gcc-4.6.0, it was cured by r159480, a generic patch
to reduce stack frame sizes.

The description <http://gcc.gnu.org/ml/gcc-patches/2010-05/msg00441.html>
didn't mention fixing any bugs, so I don't know if it actually fixed this bug
or just made it latent.
