Change bvudiv semantics based on input language (#1292)
* Change bvudiv semantics based on input language
The semantics of division by zero have changed from SMT 2.5 to SMT 2.6.
This commit sets the default options for the division semantics based on
the language version used. The input language was already kept track of
in the options, so this commit just updates the input language option
when there is a set-info command. This mirrors how the code already
deals with the output language.
Note: With this commit, set-info overwrites the option set by the user.
This is done to be consistent with the parser.
This partially fixes #1241.
* clang format
