  target/ppc: fix single-step exception regression (2021-06-03 18:10:31 +1000)

----------------------------------------------------------------
ppc patch queue 2021-06-03

Next batch of ppc target patches.  Highlights are:
 * A fix for a regression with single-step mode
 * Start of moving ppc to use decodetree
 * Implementation of some POWER10 64-bit prefixed instructions
 * Several cleanups to softmmu code
 * Continued progress towards allowing --disable-tcg
 * Fix for the POWER PEF implementation
 * Fix for LPCR handling of hotplugged CPUs
 * Assorted other bugfixes and cleanups

This patchset does contain a couple of changes to code outside my
normal scope of maintainership, related to the removal of cpu_dump and
cpu_statistics hooks.  ppc was the last target arch implementing these
at all, and they didn't really do anything there either.  The patches
should have relevant acks.
