The MDCR_EL2.TDE bit allows the exception level targeted by debug exceptions to be set to EL2 for code executing at EL0. We handle this in the arm_debug_target_el() function, but this is only used for hardware breakpoint and watchpoint exceptions, not for the exception generated when the guest executes an AArch32 BKPT or AArch64 BRK instruction. We don't have enough information for a translate-time equivalent of arm_debug_target_el(), so instead make BKPT and BRK call a special purpose helper which can do the routing, rather than the generic exception_with_syndrome helper.
