testsuite: Fix gcc.dg/vect/bb-slp-39.c on IBM Z

On IBM Z the aliasing stores are realized through one element vector
instructions, if no cost model for vectorization is used which is the
default according to vect.exp.  Fixed by changing the number of times
the pattern must be found in the dump.

gcc/testsuite/ChangeLog:

	* gcc.dg/vect/bb-slp-39.c: Change number of times the pattern
	must match for target IBM Z only.
