s390x: Support "compare biased exponent" insns CEDTR, CEXTR.
To do that properly, two new IROps are needed: Iop_CmpExpD64 and
Iop_CmpExpD128. It might seem that extracting the exponents using
Iop_ExtractExpD64/D128 and comparing the values could be used here.
But that only works for finite DFP values. Hence, the new IROps.

Patch by Maran Pakkirisamy (maranp@linux.vnet.ibm.com).
This is part of fixing BZ 307113.
