target/ppc: Add new PMC HFLAGS
Add 2 new PMC related HFLAGS:
- HFLAGS_PMCJCE - value of MMCR0 PMCjCE bit
- HFLAGS_PMC_OTHER - set if a PMC other than PMC5-6 is enabled
These flags allow further optimization of PMC5 update code, by
allowing frequently tested conditions to be performed at
translation time.
