target-arm: Add AArch64 ELR_EL1 register.
Add the AArch64 ELR_EL1 register.
Note that this does not live in env->cp15: for KVM migration
compatibility we need to migrate it separately rather than
as part of the system registers, because the KVM-to-userspace
interface puts it in the struct kvm_regs rather than making
them visible via the ONE_REG ioctls.
