On ppc, we emulate instructions that cause alignment exceptions. If we are
single-stepping an instruction and it causes an alignment exception, we
will currently do the next instruction as well before taking the
single-step exception. This patch fixes that, so we take the single-step
exception after emulating the instruction.
