1.2.6: Has Double Precision Floating Point

The macro PPC_HAS_DOUBLE is set to 1 to indicate that the PowerPC model has support for double precision floating point numbers. This is important because the floating point registers need only be four bytes wide (not eight) if double precision is not supported.
