John Baldwin 21157ad3b1 Adjust the handling of the local APIC PMC interrupt vector: 
- Provide lapic_disable_pmc(), lapic_enable_pmc(), and lapic_reenable_pmc()
  routines in the local APIC code that the hwpmc(4) driver can use to
  manage the local APIC PMC interrupt vector.
- Do not enable the local APIC PMC interrupt vector by default when
  HWPMC_HOOKS is enabled.  Instead, the hwpmc(4) driver explicitly
  enables the interrupt when it is succesfully initialized and disables
  the interrupt when it is unloaded.  This avoids enabling the interrupt
  on unsupported CPUs which may result in spurious NMIs.
