[PATCH] D110280: [modules] Fix IRGen assertion on accessing ObjC ivar inside a method.

Rebase and add a test case with `always_inline`.

Interaction between `always_inline` function and `testAccessBitField` has
revealed that we cannot avoid having expressions referencing decls from "wrong"
module. So returning a canonical ivar in name lookup is not sufficient. Mimic
`CGRecordLayout` approach and use canonical ivar in
`ASTContext::lookupFieldBitOffset`, where we look up concrete layout data.
