d3412df20a target/ppc: trigger PERFM EBBs from power8-pmu.c 
This patch adds the EBB exception support that are triggered by
Performance Monitor alerts. This happens when a Performance Monitor
alert occurs and MMCR0_EBE, BESCR_PME and BESCR_GE are set.

fire_PMC_interrupt() will execute the raise_ebb_perfm_exception() helper
which will check for MMCR0_EBE, BESCR_PME and BESCR_GE bits. If all bits
are set, do_ebb() will attempt to trigger a PERFM EBB event.

If the EBB facility is enabled in both FSCR and HFSCR we consider that
the EBB is valid and set BESCR_PMEO. After that, if we're running in
problem state, fire a POWERPC_EXCP_PERM_EBB immediately. Otherwise we'll
queue a PPC_INTERRUPT_EBB.

cb76bbc43f target/ppc: add PPC_INTERRUPT_EBB and EBB exceptions 
PPC_INTERRUPT_EBB is a new interrupt that will be used to deliver EBB
exceptions that had to be postponed because the thread wasn't in problem
state at the time the event-based branch was supposed to occur.

ISA 3.1 also defines two EBB exceptions: Performance Monitor EBB
exception and External EBB exception. They are being added as
POWERPC_EXCP_PERFM_EBB and POWERPC_EXCP_EXTERNAL_EBB.

PPC_INTERRUPT_EBB will check BESCR bits to see the EBB type that
occurred and trigger the appropriate exception. Both exceptions are
doing the same thing in this first implementation: clear BESCR_GE and
enter the branch with env->nip retrieved from SPR_EBBHR.

The checks being done by the interrupt code are msr_pr and BESCR_GE
states. All other checks (EBB facility check, BESCR_PME bit, specific
bits related to the event type) must be done beforehand.
