[mips] Provide a getter method for MCInstrInfo so that it becomes possible to access MCInstrDesc from a custom MCELFStreamer.

A "getter" method ;-)

LGTM

This change is not require any more. I realized yesterday that we can access MCInstrDesc directly via a global array defined in TargetGenInstrInfo.inc (MCInstrDesc MipsInsts[]).

lib/Target/Mips/MCTargetDesc/MipsMCCodeEmitter.h

class MipsMCCodeEmitter : public MCCodeEmitter {
   bool isMicroMips(const MCSubtargetInfo &STI) const;
 
 public:
   MipsMCCodeEmitter(const MCInstrInfo &mcii, MCContext &Ctx_, bool IsLittle)
       : MCII(mcii), Ctx(Ctx_), IsLittleEndian(IsLittle) {}
 
   ~MipsMCCodeEmitter() {}
 
+  const MCInstrInfo &getInstrInfo() const { return MCII; }
+
   void EmitByte(unsigned char C, raw_ostream &OS) const;
 
   void EmitInstruction(uint64_t Val, unsigned Size, const MCSubtargetInfo &STI,
                        raw_ostream &OS) const;
 
   void EncodeInstruction(const MCInst &MI, raw_ostream &OS,
                          SmallVectorImpl<MCFixup> &Fixups,
                          const MCSubtargetInfo &STI) const;
