This patch adds all the prerequisites for AArch64 support that didn't fit into split up patches. It extends important bits in the core cpu headers to also take AArch64 mode into account. Add new ARM_TBFLAG_AARCH64_STATE translation buffer flag indicate an ARMv8 cpu running in aarch64 mode vs aarch32 mode.
