patch

In both cases we fail because unaligned loads (or stores) are not supported.

Indeed while the testcases make sure the arrays are aligned the variable
striding makes it not so in all cases (and GCC fails to analyze it so
for some cases where it is).

I suppose XFAILing / providing alternat scan-dump for [!] vect_hw_misalign
will fix this.

Can you test the attached?
