arm64: compat: Add condition code checks and IT advance
Here's a /really nice/ part of the architecture: a CP15 access is allowed to trap even if it fails its condition check, and SW must handle it. This includes decoding the IT state if this happens in am IT block. As a consequence, SW must also deal with advancing the IT state machine.
