  1. [CHERI-RISC-V] Add a baseline test for incorrect union arguments 

    Unions that contain an int128 and a capability are passed as a single
i128 instead of as a capability or indirectly.

  2. [CHERI] Prefer capability types when lowering unions to LLVM IR types 

    This ensures that a union contain a __int128 and a capability will
be lowered as a struct with one capability field instead of as an
i128. This fixes tag stripping when passing such unions to functions
by value instead of by reference.
