Remove FIXME about considering concurrent load/store and debug entry
...
in calculating the privilege of load/stores. This is safe because it
is only the *current* debug mode state which affects load/stores,
and some new properties have been added to ensure load/stores can
not be in aphase at the point debug mode is entered/exited (which
is achieved by delaying the trap). Therefore there is no way for
debug entry to inadvertently boost the privilege of an executing
U-mode load/store.
Also rename a confusingly-named signal for an unsquashable bus
transfer in stage 2 that delays IRQ entry.
