The PMU raises a performance monitor exception (causing an interrupt
when MSR[EE]=1) when MMCR0[PMAO] is set, and lowers it when clear.
Wire this up and implement the interrupt delivery for books. Linux perf
record can now collect PMI-driven samples.
fire_PMC_interrupt is renamed to perfm_alert, which matches a bit closer
to the new terminology used in the ISA and distinguishes the alert
condition (e.g., counter overflow) from the PERFM (or EBB) interrupts.

BookS msgsndp instruction to self or DPDES register can cause SDOOR
interrupts which crash QEMU with exception not implemented.
Linux does not use msgsndp in SMT1, and KVM only uses DPDES to cause
doorbells when emulating a SMT guest (which is not the default), so
this has gone unnoticed.

ppc hypervisors turn HEAI interrupts into program interrupts injected
into the guest that executed the illegal instruction, if the hypervisor
doesn't handle it some other way.
The nested-hv implementation failed to account for this HEAI->program
conversion. The virtual hypervisor wants to see the HEAI when running
a nested guest, so that interrupt type can be returned to its KVM
caller.

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.

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.
