When -triple is windows, SelectionDAGLegalize process Legalizing br_jt, would generate ISD::JUMP_TABLE_DEBUG_INFO. Then Mips process emitInstruction, would think JUMP_TABLE_DEBUG_INFO is a pseudo instruction and generate an error `Pseudo opcode found in emitInstruction()`. This instruction `TargetOpcode::JUMP_TABLE_DEBUG_INFO` is only used to note jump table debug info, so we can ignore it when Mips emit instruction. Fix #134916.
