[ Upstream commit 16ccadefa295af434ca296e566f078223ecd79ca ]
Add emulate_ops.is_canonical_addr() to perform (non-)canonical checks in the emulator, which will allow extending is_noncanonical_address() to support different flavors of canonical checks, e.g. for descriptor table bases vs. MSRs, without needing duplicate logic in the emulator.
No functional change is intended.
