target-ppc: Define FPR Pointer Type for Helpers

Browse Source 
Define a floating pointer register pointer type in the PowerPC
helper header.  The type will be used to pass FPR register operands
to Decimal Floating Point (DFP) helpers.  A pointer is used because
the quad word forms of PowerPC DFP instructions operate on adjacent
pairs of floating point registers and thus can be thought of as
arrays of length 2.
