The attached patch makes the htm tests on s390 less sensitive to
spurious abort. Please check the commit comment for details. The
modified tests have been run once on a zEC12.
Ciao

Subject: [PATCH] S390: Lower requirements for successful htm tests.
Due to spurious aborts, requiring four successful tests out of five fails too
often; accept four out of seven instead.
Reduce number of warmup passes.
