S/390: Use signaling FP comparison instructions
dg-torture.exp=inf-compare-1.c is failing, because (qNaN > +Inf)
comparison is compiled to CDB instruction, which does not signal an
invalid operation exception. KDB should have been used instead.
This patch introduces a new CCmode and a new pattern in order to
generate signaling instructions in this and similar cases.
