Previously `TICK_BUMP_BY` was defined as

```c
 #define TICK_BUMP_BY(ctr,n) CLong[ctr] = CLong[ctr] + n
```

Yet the tickers themselves were defined as `StgInt`s. This happened to
work out correctly on Linux, where `CLong` is 64-bits. However, it
failed on Windows, where `CLong` is 32-bits, resulting in #18782.

Fixes #18783.
