This only works on integrals for now.
Add four new opcodes, `Inc`, `IncPop`, `Dec` and `DecPop`. The `*Pop` variants don't leave anything on the stack and exist because the common case is that the result is unused.
There are still a few corner cases left like floating values, pointers, and over/underflow handling.
