10dc3a8e91 [clang][Interp] Fix empty InitListExprs for unions 
We still need to handle Inits.size() == 0, but we can do that earlier.

af6812085c [clang][Interp] Fix initializing a union from an InitLIstExpr 
We can't just count the field to initialize but need to consult the
InitListExpr to give us the right field.

9d70975c7a [clang][Interp][NFC] Remove an assertion that's too strong 
Both types need to boil down to a vector type with the same length
and their element types need to match, but we still can't compare
them with == since they might be sugared, etc.

This reverts commit 1c7673b91d4d3bab4e296f5c67751d3879fb21a2.

Unfortunately, this one is broken because de04e6cd90b891215f1dfc83ec886d037a7c2ed0
has been reverted.

1c7673b91d [clang][Interp] Fix locals created in ExprWithCleanups

so we can attach a local temporary variable to the right scope.

15f02723d4 [clang][Interp] Improve support for virtual bases 
Fix initializing virtual bases. We only consider their base size,
not their virtual size because they get flattened into the Record
hierarchy when we create them. Fix that and also virtual
derived-to-base casts.

[clang][Interp] Integral pointers (#84159) 
This turns the current `Pointer` class into a discriminated union of
`BlockPointer` and `IntPointer`. The former is what `Pointer` currently
is while the latter is just an integer value and an optional
`Descriptor*`.

The `Pointer` then has type check functions like
`isBlockPointer()`/`isIntegralPointer()`/`asBlockPointer()`/`asIntPointer()`,
which can be used to access its data.

Right now, the `IntPointer` and `BlockPointer` structs do not have any
methods of their own and everything is instead implemented in Pointer
(like it was before) and the functions now just either assert for the
right type or decide what to do based on it.

This also implements bitcasts by decaying the pointer to an integral
pointer.

`test/AST/Interp/const-eval.c` is a new test testing all kinds of stuff
related to this. It still has a few tests `#ifdef`-ed out but that
mostly depends on other unimplemented things like
`__builtin_constant_p`.
