Merge pull request #1982 from waywardmonkeys/avoid-const-params-in-decls 
Avoid const params in decls.

Bruce Mitchener 2016f48dc9 Avoid const params in decls. 
Const-qualification of parameters only has an effect in function
definitions.

Arie Gurfinkel 58d93d8907 Fix add external lemmas to solver even if use_bg_invs=false 
spacer.use_bg_invs controls how user-supplied invariants are used.
However, the user expects them to be used independent of the option.

Michał Janiszewski cfd0486582 Catch exceptions by const-reference 
Exceptions caught by value incur needless cost in C++, most of them can
be caught by const-reference, especially as nearly none are actually
used. This could allow compiler generate a slightly more efficient code.

Arie Gurfinkel 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

Arie Gurfinkel bd63458778 Shuffle assumptions on every call 
Order of assumptions appears to make a huge difference on what lemmas
