Debug Info Finder: use processDeclare and processValue to list debug info

MDNodes used by DbgDeclareInst and DbgValueInst.

Another 16 testing cases failed and they are disabled with
-disable-debug-info-verifier.
A total of 34 cases are disabled with -disable-debug-info-verifier and will be
corrected.
