Also make IRGenModule::getAddrOfTypeMetadata() more clear that a GEP is being forced and optional aliasing is involved rather than imply that full metadata always requires a GEP (which it does not).

@swift-ci please smoke test

For whatever it may be worth, I found the "adjustment index" differences between the two functions to be quite confusing for a while. I assumed that it was code duplication but I was wrong.

I can live with fullMetadata as the variable name. I just want the comments to get better in the latter function.

@swift-ci please smoke test
