tcg: Zero extend 32-bit addresses for TCI

tcg: Zero extend 32-bit addresses for TCI

For native code generation, zero-extending 32-bit addresses for
the slow path helpers happens in tcg_out_{ld,st}_helper_args,
but there isn't really a slow path for TCI, so that didn't happen.

Make the extension for TCI explicit in the opcode stream,
much like we already do for plugins and atomic helpers.
