The functions all call foo and therefore need a stack frame what makes
them subject to shrink wrapping. Also all the additional instructions
in the function body makes it fragile wrt instruction scheduling. Just
set a global variable instead to circumvent this.
Committed to mainline.

* gcc.target/s390/zvector/vec-cmp-2.c
(all_eq_double, all_ne_double, all_gt_double)
(all_lt_double, all_ge_double, all_le_double)
(any_eq_double, any_ne_double, any_gt_double)
(any_lt_double, any_ge_double, any_le_double)
(all_eq_int, all_ne_int, all_gt_int)
(all_lt_int, all_ge_int, all_le_int)
(any_eq_int, any_ne_int, any_gt_int)
(any_lt_int, any_ge_int, any_le_int): Set global variable instead
of calling foo(). Fix return type.
