  Changed paths:

    M llvm/utils/TableGen/InstrInfoEmitter.cpp

  Log Message:
  -----------
  [TableGen] Declare <TargetName>RegClassByHwModeTables in MC header (#223292)

When a target uses RegClassByHwMode in CompressPat, the generated
functions reference <TargetName>RegClassByHwModeTables.

Declare it under GET_INSTRINFO_MC_HELPER_DECLS (<Target>MCTargetDesc.h)
so it is visible to MC-layer users such as RISCVBaseInfo.cpp.

Fixes: 700d1f029d00 ("[TableGen] Support RegClassByHwMode in
CompressPat")
