ARMv8.4 adds the mandatory FEAT_TLBIOS and FEAT_TLBIRANGE.
They provides TLBI maintenance instructions that extend to the Outer
Shareable domain and that apply to a range of input addresses.
Changes from v1 to v2:
o Split new instructions into different ARMCPRegInfo sections, and only
add them if ID_AA64ISAR0.TLB indicates they're supported.
o Improve the performance of the new code in cputlb.c.
Testing:
o Ran scripts/checkpatch.pl: functions in exec-all.h fail,
but I think that's acceptable?
o Built all targets
o Ran test code that executed the new instructions
o Ran "make test": a qtest-sparc repeatedly timed out,
but that's unlikely to be due to my changes.
