MIR Parser: Extract the MDNode parsing code into a separate method. NFC.
This change would allow the machine instruction parser to reuse this method when parsing the metadata node for the machine instruction's debug location property. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@242934 91177308-0d34-0410-b5e6-96231b3b80d8
