Add the following Decimal Floating Point (DFP) instructions for PowerPC.
dadd, daddq, dsub, dsubq
In order to add these instructions a new register class for a pair
of floating point registers is added.
This patch is only to allow the user to specify the instructions in
assembly. There is no scheduling or patterns for the instructions.
