lib+proof+autocorres: consolidate when[E]/unless[E]_wp naming 
wp rules for most operators such as return, get, gets are named
return_wp, get_wp, etc. Then when, whenE, unless, unlessE operators had
an additional hoare_.. prefix that this commit removes for more
consistency.

Gerwin Klein 96c934f6a5 ainvs: consolidate do_machine_op lemmas in KHeap 
Clean up KHeap_AI. It turns out that almost all do_machine_op lemmas
proved here are crunchable, so move them all into on place.

This only proves lemmas originally already in KHeap_AI. It would likely
make sense to collect general do_machine_op lemmas from other places
in AInvs here as well.

Gerwin Klein 24c0c5c390 spec+proof: use generated config constants 
This includes replacing previous ASpec names for such constants with
the names used in Haskell/ExecSpec to avoid duplication. This also
makes some of the proofs slightly more generic.
