Generated interfaces for Clang modules used to try printing normal
comments between decls extracted from the header text. That was because
doc-comment was not common in C/ObjC headers. But mainly because of
"import as member feature" Clang decls aren't printed in the order as
they appear in the header file, the logic determinig which comment
belongs to which decl was not working property. We've decided to remove
that feature and only print the proper doc-comments as it has been
getting common.

Objective-C protocols unlike their Swift counterparts could be
nested in other types, so `computeNominalType` has to fetch a
parent for such protocols (if any) just like importer does.

The triple name aarch64_32 does not actually name a valid platform. The
actual platform (and valid triple arch string, confusingly enough) is
arm64_32. Remap between the two to correct for this difference.

It's a terrible idea to support this in the long run, but in the short
term we should at least know what the compiler does in these situations.
