b9455c3692 #6999 deal with implicit assumptions, more robust pattern matching 
The code is making some assumptions that arrays are 1-dimensional. This is not generally true.
Introducing pattern matching to ensure the assumption is met.
Avoid get_arg(..) especially when there is an approach based on pattern matching recognizers.

65a8c162f5 add E(T) functionality for bv and ac functions 
Add an option to register EUF modulo theories,
The current theory with a unit test is BV.
The arithmetic theory plugs into an AC completion. It is partially finished, pending setting up testing and implementing handling of shared terms.
