Add a flag to enable/disable tracking arrays for constant domains

This PR adds config param trackArraysForConstDomains = false, which can be
set to true at compile time to track arrays even if we know that the domain is
constant. This is added as a stopgap measure in case there is a bug in
determining whether a domain is constant or not.

Also adds a test for the flag’s behavior.
