testsuite: Fix pr83403-{1,2}.c on IBM Z

For z10 and newer inner loops are completely unrolled which means store
motion is not applied.  Reverting max-completely-peeled-insns to the
default value fixes these testcases.

gcc/testsuite/ChangeLog:

	* gcc.dg/tree-ssa/pr83403-1.c: Revert
	max-completely-peeled-insns to the default value on IBM Z.
	* gcc.dg/tree-ssa/pr83403-2.c: Likewise.
