The following C-state flags are currently mutually-exclusive and should not
be combined:
  * IRQ_ENABLE
  * IBRS
  * XSTATE

There is a warning for the situation when the IRQ_ENABLE flag
is combined with the IBRS flag, but no warnings for other combinations.
This is inconsistent and prone to errors.

Improve the situation by adding warnings for all the unexpected
combinations. Add a couple of helpful commentaries too.
