Convert V1TImode register to TImode in debug insn
TImode register referenced in debug insn can be converted to V1TImode by
scalar to vector optimization. When converting a TImode store to V1TImode,
we need to check all debug insns on its use chain to convert the V1TImode
register to SUBREG TImode if source register is undefined.
