[PATCH][AArch64][test] Disable vector cost model on vect_ctz_1.c test

[Kyrill Tkachov]

Hi all,

The second scan-assembler test for clz\tv\[0-9\]+\.2s FAILs on this test 
due to vector costs on A57.
The vectorisation happens for cortex-a53 and thunderx.
I think this test was supposed to test the capability of vectorising clz 
rather than the tuning decision of whether to (though I imagine people 
can argue the other way),
so this patch adds an -fno-vect-cost-model to it to get it to always 
vectorise.

This way the test passes on all -mcpu options.

Ok for trunk?

Thanks,
Kyrill

      dg-options.
