Do not crash when trying to compute x && y or x || y where x and y are
of a vector type.
For now we do not seem to properly model operations with vectors. In particular,
operations && and || on a pair of vectors are not short-circuit, unlike regular
logical operators, so even our CFG is incorrect.
Avoid the crash, add respective FIXME tests for later.
