Failing test case

Here's another instance of the failure that has been reported before.

The attached test case fails when built with -O1 -ftree-vectorize -mfpu=neon

This was tested with a compiler built from gcc-4.7-20120225.tar.bz2 sources.

...
bin/armv7hl-pc-linux-gnueabi-gcc -O1 -ftree-vectorize -mfpu=neon
minimal-testcase.i -c
minimal-testcase.i: In function 'lsp_quant_nb':
minimal-testcase.i:14:6: internal compiler error: in vect_is_simple_use_1, at
tree-vect-stmts.c:6057
Please submit a full bug report,
with preprocessed source if appropriate.
...

This does not fail with gcc 4.6.3.
