Debug Info testing case: update uuid testing case to check against Itanium.

Right now, the output for Itanium vs. Microsoft is the same. Once we start
calling mangler to get the unique identifier, this testing case will require
support for uuid mangling.

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.

ObjectiveC migrator: In suggesting 'instancetype' use clang's
hasRelatedResultType() as it knows of methods which have
related result type by default. Such methods do not need
a redundant 'instancetype'.
