[Bug tree-optimization/22158] New: char global_var[] = "larger than 32 bytes"; uses silly amounts of alignment even with -Os

["vda at port dot imtp dot ilyichevsk dot odessa dot ua" <gcc-bugzilla at gcc dot gnu dot org>]

static char *s0 = "000000000000000000000000000000000000000000000000";
static char s1[] = "111111111111111111111111111111111111111111111111";
static char *s2 = "000000000000000000000000000000000000000000000000";
static char s3[] = "111111111111111111111111111111111111111111111111";

void f(char*);
void g() {
    f(s0);
    f(s1);
    f(s2);
    f(s3);
}

s1 and s2 are aligned on 32 bytes even with -Os, while s2 and s4 are not.
