ppc: Convert GPR moves to TCG

Replace op_load_gpr_{T0,T1,T2} and op_store_{T0,T1,T2} with tcg_gen_mov_tl.
Introduce TCG variables cpu_gpr[0..31].

For the SPE extension, assure that ppc_gpr_t is only uint64_t for ppc64.
Introduce TCG variables cpu_gprh[0..31] for upper 32 bits on ppc and helpers
gen_{load,store}_gpr64. Based on suggestions by Aurelien, Thiemo and Blue.
