Edward Pierzchalski f067068a88 asmrefine: improve initial debugging experience. 
Adds a 'debug' configuration type to the main ProveSimplToGraphGoals
functions. Configuration lets the user control which functions will be
tested, and logs which functions fail testing.

Adds a 'single step' debug tactic for use in TestGraphRefine, and
demonstrates a few useful initial ML tactic for e.g. narrowing down
which subgoals are failing, and how to inspect a successful subgoal.

Victor Phan 67bba7edc3 lib, x64 crefine: remove word lemma unat_ucast_8_64 
unat_ucast_8_64 states that upcasting an 8 word to a 64 word does not
changes its value. We have a generic lemma for this which can be
specialised to this lemma: unat_ucast_up_simp[where 'a=8 and 'b=64,
simplified].

Corey Lewis 9a9c6320be lib: various crunch improvements 
The main one is that crunch now uses wpsimp when determining whether a goal
can already be solved, instead of just wp. Crunch can also now use wps
when proving a goal and will now always ignore a constant if told to, even
if it is the top-level constant being crunched.

Corey Lewis dd48e0d899 proof: update for wp changes 
Updated 'wp_once' to 'wp (once)' and removed several stray uses of 'wp_trace'.

Corey Lewis f757e0ca5b lib: wp cleanup and parser improvements 
The main visible change is from wp_trace', 'wp_once' and 'wp_once_trace' to
'wp (trace)', 'wp (once)' and 'wp (once, trace)'. The option for printing a
warning for unused supplied wp rules has also been removed.

MiladKetabi acbc08b836 clean-ups done during proof update for the jira issue SELFOUR-1187: seL4 setPriority should attempt a direct schedule 2019-10-06 18:31:19 +11:00
MiladKetabi d934d25269 proof update for SELFOUR-1187: seL4 setPriority should attempt a direct schedule 
Prior to this commit the kernel would always trigger a full reschedule
on setPriority. This change allows the kernel to attempt a direct
switch, avoiding invoking the scheduler.
