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