When fiddling around with vector lowering I found the following
adjusted testcase helpful testing proper vector lowering of
word_mode vector plus.
Tested on x86_64-unknown-linux-gnu, applied.
Richard.

* gcc.c-torture/execute/20050604-1.c: Adjust to be a better
test for correctness of vector lowering.
