ppc: Remove unncesessary function declarations

Browse Source 
ppc_opcode16 and other functions are only needed in the implementation in
ppcexec.cpp, they don't need to be in the header.

fp_return_double and fp_return_uint64 have no uses (as of 2141a72b87)
can can thus be removed altogether.

Similarly ppc_fpu_off has no uses (as of bb3f4e596e)
and can be removed.
