The definition of the pal_process_state_info_s structure
misses out some useful pieces (e.g. the "mi" bit which indicates
whether we should call PAL_MC_ERROR_INFO to get more details).

Worse yet, some of the bits are in the wrong places (cc/tc/bc).

See Volume 2 of "Intel Itanium Architecture Software Developer's
Manual".  (In the Rev 2.1 October 2002 edition, p. 2:268 and 2:276).
