Support for enums with more than 32bit
Original issue created by @PhilippWendler on 2017-08-22 at 15:30:49, last modified on 2017-08-22 at 15:30:49
By assigning specific values to enum constants, we can force enum types to be larger than 32bit.
This leads to a crash in the predicate analysis, both with linear and bitprecise encoding:
Exception in thread "main" java.lang.AssertionError: numeral value 137438953408 is too big for bitvector of length 32.
