The M-profile architecture specifies that the DebugMonitor exception
should be initially disabled, not enabled. It should be controlled
by the DEMCR register's MON_EN bit, but we don't implement that
register yet (like most of the debug architecture for M-profile).
Note that BKPT instructions will still work, because they
will be escalated to HardFault.
