Following support from the previous patches in this stack being added for variadic DBG_INSTR_REFs to exist, this patch modifies LiveDebugValues to handle those instructions. Support already exists for DBG_VALUE_LISTs, which covers most of the work needed to handle these instructions; this patch only modifies the transferDebugInstrRef function to correctly track them.
