  Log Message:
  -----------
  Align mach exception data before accessing it

The mach exception data may not be doubleword aligned when we receive
it.  We use memcpy to align it later in this method when we save
the data, but for printing the value at the top, we need to do the
same or ubsan can trigger when LOG_EXCEPTIONS is enabled in
debugserver.
