Slava Pestov 32316559f8 AST: Stored property accessors on non-Objective-C derived classes can be transparent ...

In 74d979f0ac, the policy was changed
so that only value type accessors are ever marked transparent, and
not class accessors.

This was intended to fix a bug where inlining an accessor of an
Objective-C-derived class across module boundaries caused a linker
failure because the accessor referenced a field offset variable,
which has hidden visibility.

However, this also caused a performance regression for Swift native
classes. Bring back the old behavior for Swift native classes in
non-resilient modules.

Fixes <rdar://problem/29884727>.
