I was thinking about a portable way to test this does not happen again
but all I could think of was looking at the asm but now I just
remembered about the alignof expressions.  Here is a testcase which
passes now but failed before the patch:
float x __attribute__((aligned(128),vector_size(8)));
int f[__alignof__(x) == 128?1:-1];

Thanks,
