[DebugInfo] Fix updateDbgUsersToReg to support DBG_VALUE_LIST

This patch modifies updateDbgUsersToReg to properly handle
DBG_VALUE_LIST instructions, by replacing the hard-coded operand indices
(i.e. getOperand(0)) with the more general getDebugOperandsForReg(), and
updating the register for all matching operands.
