Treat guarded_spec_body like Spec in asmrefine.

The parser now emits guarded_spec_body for underspecified functions,
not Spec. SimplExport now treats them the same.

Fiddling const global unfold in graph refine.

Try to avoid emitting const-globals via memory.
...
Sometimes it's simpler to access an unknown field of a const
global by just computing the offset from its symbol in memory
and assuming the relevant words are in the .rodata section. But
for known fields, it's easier to just figure out what the
constant value is. This complicates the proof slightly, since
it has to guess which case it is in.

Restore global valid assertions in graph refine.
...
The global-object pointer validity assertion is now created at
export time, and the graph refine mechanism now proves them. It
seems they were forgotten about once again in adjusting the globals
logic.

SEL4GraphRefine now completed.
...
These final changes complete the SEL4GraphRefine process. Some
cleanup remains to be done, especially in SEL4GlobalsSwap, but the
process is now mature and working, and the testing code
in SEL4GraphRefine can be discarded.
Success depends on seL4 commit 97d6bc96d54f1f0beafb25033b03b57ba54a5113
which is compatible with crefine and will be included in the repo
manifest immediately.

Move burden of 'halt' proof, use less modifies.
...
In detail:
- add a general user-specified exception to c_exntype
(for use in tools like Substitute)
- wrap calls to 'halt' in Guard {}, making it clearer that
halt is never called, simplifying asmrefine
- repair halt changes in crefine
- avoid use of some suspicious 'modifies' properties in crefine
which were generated by the parser for functions where inline
ASM blocks have been elided, and which may be inaccurate.
