Update vect-35.c testcase

Update vect-35.c testcase

[Jan Hubicka]

Hi,
We now determine depnedencies across union fields correctly so 2 instead
of 1 loops are vectorized.

regtsted x86_64-linux, comitted.

	* gcc.dg/vect/vect-35-big-array.c: Excpect 2 loops to be vectorized.
	* gcc.dg/vect/vect-35.c: Excpect 2 loops to be vectorized.
