[PATCH/RFA] Fix up gcc.dg/vect/pr30858.c expected output

All,

The attached patch corrects the expected output of the
gcc.dg/vect/pr30858.c testcase.

Historically it has expected the output "Unknown def-use cycle pattern." 
just once.

However, recent changes to GCC for ARM targets means that vectorization 
is attempted twice once with a vector size of 128-bits and once with a 
vector size of 64-bits.  This means that the output appears more than  once.

The patch works around this by making the testcase expect one or more 
instances of "Unknown def-use cycle pattern"

Can someone review please?

Thanks,

Matt
