reduced testcase

There are three testcases that ICE with a very similiar message:

$ gcc -O -mavx -ftree-vectorize gcc.target/i386/avx-vcmppd-256-1.c
gcc.target/i386/avx-vcmppd-256-1.c: In function 'do_test':

As the ICEs look quite similiar, I am opening just one PR for it.

Compiler output:
$ gcc -O -ftree-vectorize testcase.c 
testcase.c: In function 'foo':
testcase.c:9:10: internal compiler error: in gen_vcondv2div2df, at

Maybe related to the "Vector Comparison patch".
