Debug Info: update interface for CreateEnumType and getOrCreateRecordFwdDecl.

Both functions will take a Type pointer instead of a Decl pointer. This helps
with follow-up type uniquing patches, which need the Type pointer to call
CXX mangler to generate unique identifiers.

No functionality change.
