translate-c: non-wrapping operator for pointer arithmetic
According to C11 6.5.6.8, pointer arithmetic may not overflow. In fact,
it may not even go more than 1 past the end of an object, or UB occurs.
This is the same as Zig pointer arithmetic semantics, and so the
`+` and `+=` operators rather than `+%` and `+%=` are appropriate for
C-translated pointer arithmetic.
