Add a new file (dfp_helper.c) to the PowerPC implementation for Decimal Floating Point (DFP) emulation. This first version of the file declares a structure that will be used by DFP helpers. It also implements utilities that will initialize such a structure for either a long (64 bit) DFP instruction or an extended (128 bit, aka "quad") instruction. Some utility functions are annotated with the unused attribute in order to preserve build bisection.
