powerpc: Add support for additional FSCR-managed facilities

Add support to enable, save, and restore the following facilities:
* Target Address Register (bctar) -- seemingly just another register to
  branch to.
* Event-based branching -- an interrupt-like userspace event handler
  subsystem.
* Load-monitored facility -- A facility that allows monitoring a range of
  physical memory, and triggering an event on access.  Targeted to garbage
  collection software features.
