This opcode was only used to mark unreachable code for plive to use. plive now uses the SSA representation, so it knows locations are unreachable because they are ends of Exit blocks. It doesn't need these opcodes any more. These opcodes actually used space in the binary, 2 bytes per undef on x86 and more for other archs. Makes the amd64 go binary 0.2% smaller.
