For z10 and newer inner loops are completely unrolled which leaves no
inner loops to jam which renders this testcase to fail. Reverting
max-completely-peel-times to the default value fixes this testcase.
gcc/testsuite/ChangeLog:
* gcc.dg/unroll-and-jam.c: Revert max-completely-peel-times to
the default value on IBM Z.
