This will result in faster Disable/Enable code since the
system trap handler does not need to decode which function
the user wants. Besides the IRQ disable/enabled can now
be inline which avoids the caller to take into account that
o0-o7+g1-g4 registers are destroyed by trap handler.
It was also possible to reduce the interrupt trap handler by
five instructions due to this.
