The branch target exception for guarded pages has high priority, and only 8 instructions are valid for that case. Perform this check before doing any other decode. Clear BTYPE after all insns that neither set BTYPE nor exit via exception (DISAS_NORETURN). Not yet handled are insns that exit via DISAS_NORETURN for some other reason, like direct branches.
