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.

Mitchell Buckley 7180ee4e70 refine: Standardise names of some corres lemmas 
Ideally all corres lemmas of the form
`corres rrel P P' my_abstract_function myHaskellFunction`
should be named `myHaskellFunction_corres`.

This commit renames over 200 lemmas to match this style.

Corey Lewis 008969fc02 lib proof: reorder the assumptions of corres_split 
Currently this just modifies the rule but not any of the proofs that use
it. The old version is kept for now but should be removed once all of
the proofs are updated.

Victor Phan 966734c69b Collect abstract lemmas in Refine 
Create ArchMove_R.thy for transporting arch specific lemmas (and generic
lemmas that are used somewhat specifically by one architecture) to theory
files before Refine.

Create Move_R.thy as an arch generic Refine theory file for transporting
generic lemmas to theory files before Refine.

Also delete some lemmas that have existed earlier already or are not
needed.

Rename Move.thy in CRefine to Move_C.thy for consistency.
