0035d9b8cb Background external invariants 
Background external invariants are constraints that are assumed to be
true of the system. This commit introduces a mode in which
background invariants are used only duing inductive generalization
and lemma pushing, but not during predecessor computation.

It is believed that this will be more efficient used of background
external invariants since they will not be able to disturb how
predecessors are generalized and computed.

Based on a patch by Jorge Navas
