powerpc/64: Fix update forms of loads and stores to write 64-bit EA
When a 64-bit processor is executing in 32-bit mode, the update forms of load and store instructions are required by the architecture to write the full 64-bit effective address into the RA register, though only the bottom 32 bits are used to address memory. Currently, the instruction emulation code writes the truncated address to the RA register. This fixes it by keeping the full 64-bit EA in the instruction_op structure, truncating the address in emulate_step() where it is used to address memory, rather than in the address computations in analyse_instr().
