3c31cde9 - CodeGen: Handle bundled instructions in two-address-instructions pass (#166212)

CodeGen: Handle bundled instructions in two-address-instructions pass (#166212) If the instruction with tied operands is a BUNDLE instruction and we handle it by replacing an operand, then we need to update the corresponding internal operands as well. Otherwise, the resulting MIR is invalid. The test case is degenerate in the sense that the bundle only contains a single instruction, but it is sufficient to exercise this issue.
