[Bug tree-optimization/34038] 176.gcc segfaults when compiled with -O2 -ftree-vectorize -maltivec

The failure goes away with -mabi=altivec, which is not the default with -m32. 
I had never seen this failure in my earlier testing on powerpc64-linux because
whenever I used -maltivec I also used -mabi=altivec.  It's not clear to me if
it's legitimate to use -maltivec, or -mcpu with machines that imply -maltivec,
without also using -mabi=altivec when the code will use AltiVec registers.
