Also added some comments to SLEEP As QEMU treats internal and external interrupts the same, WEVT is a SLEEP that works for user mode if the Usermode Sleep Flag is set Without SMP, WLFC is like WEVT, but only sleeps if LF is set. WLFC should be revisited when appropriate Signed-off-by: Bruno Mauricio <[email protected]>

Implemented instructions WEVT and WLFC as per issue #159
As QEMU treats internal and external interrupts the same, WEVT is just a SLEEP that works outside kernel mode if the Usermode Sleep Flag is set.
Without SMP, WLFC is like WEVT, but only sleeps if LF is set. As it is slightly more complex, a test was added since "sleep" instruction tests won't cover this.
WLFC should be revisited when appropriate. Because of that I will not close the issue for the time being and added a comment in its implementation.
