 FYI, I just checked in a change to the mips64 gdb simulator code so
 that it will do checking of values (for many, but certainly not all
 8-) which are allowed to produce UNPREDICTABLE results.
 
 This causes 27 gcc (g++, actually) tests which previously passed to
 fail, due to UNPREDICTABLE behaviour:
