We used to always flush the TLB when changing relocation mode in
MSR:IR and MSR:DR (ie. MMU on/off for Instructions and Data).
We don't anymore since we have split mmu_idx for instruction and data.
However, since we hard code the mmu_idx in the translated code, we
now need to also make sure MSR:IR and MSR:DR are part of the hflags
used to tag translated code, so that we use different translated
code for different MMU settings.
Darwin gets hurt by this problem.
