[clang][Interp] Consider bit width in IntegralAP::toAPSInt() ( #71646 )
...
In `Interp.h`, when a add/sub/mul fails, we call this code and expect to
get an `APSInt` back that can handle more than the current bitwidth of
the type.

IsSigned.

[clang][Interp] Fix IntAP(s) to IntAP(s) casts ( #69915 )
...
This was still assert(false)'ed out, it's for casts between two IntAP/IntAPS expressions.
We can't just short-circuit for FromT == ToT because we need to consider the bitwidth when doing the cast.

[clang][Interp] Support AddOffset with 128bit offsets ( #68679 )

We do a similar thing a few lines above for `Index`:
```c++
// Get a version of the index comparable to the type.
T Index = T::from(Ptr.getIndex(), Offset.bitWidth());
```

[clang][Interp] Add basic support for _BitInt ( #68069 )
...
Make sure we pass the expected bitwidth around when casting to
IntAP/IntAPS.
This makes it easier to test the `IntegralAP` code for different bit
widths than 128.
