  Log Message:
  -----------
  Reapply "[clang][bytecode] Diagnose pointer subtractions of elements … (#209998)

…of different arrays" (#209969)

This reverts commit 745b946cbbf30708044b4a2c4a7726d0c02ca0de.

Use only one `fold()` for the virtual base offset assertions.
The pointer subtraction _is_ invalid, but the current interpreter
doesn't diagnose it since the `LValueDesignator`s are invalid.
