[PATCH] testsuite: Fix unroll-and-jam.c on IBM Z

[Stefan Schulze Frielinghaus via Gcc-patches]

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.

Ok for mainline?
