// Verify that splitting a two-address DS exchange normalizes all three of its
// VGPR roles against their own incoming banks. Unlike a DS load, the exchange
// carries {Dst, Src0, Src1}, and mode 0x41 gives them a mix of banks: the
// destination tuple and the address are bank 1 while the data operands are
// bank 0. Rebasing every role from a single assumed bank would silently
// redirect the address or the data.
