Correct these issues with the handling of CP0.Status for MIPSr6:
* only ignore the bit pattern of 0b11 on writes to CP0.Status.KSU, that
is for processors that do implement Supervisor Mode, let the bit
pattern be written to CP0.Status.UM:R0 freely (of course the value
written to read-only CP0.Status.R0 will be discarded anyway); this is
in accordance to the relevant architecture specification[1],
* check the newly written pattern rather than the current contents of
CP0.Status for the KSU bits being 0b11,
* use meaningful macro names to refer to CP0.Status bits rather than
magic numbers.
