Implement PowerPC slbmfee and slbmfev instructions
For a 64-bit PowerPC target, qemu correctly implements translation through the segment lookaside buffer. Likewise it supports the slbmte instruction which is used to load entries into the SLB. However, it does not emulate the slbmfee and slbmfev instructions which read SLB entries back into registers. Because these are only occasionally used in guests (mostly for debugging) we get away with it. However, given the recent SLB cleanups, it becomes quite easy to implement these, and thereby allow, amongst other things, a guest Linux to use xmon's command to dump the SLB.
