Nathan Whitehorn bc96dccc69 Fix final bugs in memory barriers on PowerPC:
- Use isync/lwsync unconditionally for acquire/release. Use of isync
  guarantees a complete memory barrier, which is important for serialization
  of bus space accesses with mutexes on multi-processor systems.
- Go back to using sync as the I/O memory barrier, which solves the same
  problem as above with respect to mutex release using lwsync, while not
  penalizing non-I/O operations like a return to sync on the atomic release
  operations would.
- Place an acquisition barrier around thread lock acquisition in
  cpu_switchin().
