ARM: kprobes: Reject 16-bit Thumb SETEND, CPS and BKPT instructions
These are very rare and/or problematic to emulate so we will take the easy option and disallow probing them (as does the existing ARM implementation). Rejecting these instructions doesn't actually require any entries in the decoding table as it is the default case for instructions which aren't found.
