  hw/ppc/pnv: Use error_report instead of hw_error if a ROM file can't be found

ppc patch queue 2017-02-02

This obsoletes ppc-for-2.9-20170112, which had a MacOS build bug.

This is a long overdue ppc pull request for qemu-2.9.  It's been a
long time coming due to some holidays and inconveniently timed
problems with testing.  So, there's a lot in here:

    * More POWER9 instruction implementations for TCG
    * The simpler parts of my CPU compatibility mode cleanup
        * This changes behaviour to prefer compatibility modes over
          "raW" mode for new machine type versions
    * New "40p" machine type which is essentially a modernized and
      cleaned up "prep".  The intention is that it will replace "prep"
      once it has some more testing and polish.
    * Add pseries-2.9 machine type
    * Implement H_SIGNAL_SYS_RESET hypercall
    * Consolidate the two alternate CPU init paths in pseries by
      making it always go through CPU core objects to initialize CPU
    * A number of bugfixes and cleanups
    * Stop the guest timebase when the guest is stopped under KVM.
      This makes the guest system clock also stop when paused, which
      matches the x86 behaviour.
    * Some preliminary cleanups leading towards implementation of the
      POWER9 MMU.

There are also some changes not strictly related to ppc code, but for
its benefit:

    * Limit the pxi-expander-bridge (PXB) device to x86 guests only
      (it's essentially a hack to work around historical x86
      limitations)
    * Some additions to the 128-bit math in host_utils, necessary for
      some of the new instructions.
    * Revise a number of qtests and enable them for ppc
