beec309c9d AST: Fix debug info mangling of opaque result types with @_originallyDefinedIn 
If a function's parameter or return types involve nominal types that
have been moved across modules using @_originallyDefinedIn, we must
take care to always mangle the opaque result type's name using the
original module names and not the current module names.

This was a problem with DWARF mangling, which normally disables
@_originallyDefinedIn for other purposes. Make sure to always
temporarily re-enable it when mangling an opaque result type.

Fixes rdar://problem/93822207.

7b1d4df8bc ModuleInterface: Fix decl attribute corruption in private swiftinterfaces 
Erroneous declaration attributes were sometimes being printed in the private swiftinterfaces of modules because the changes from https://github.com/apple/swift/pull/42276 were effectively corrupting the attribute list for any decl with sythesized conformances (e.g. `Equatable`, `Hashable`). It is necessary to clone the attributes before adding them to the synthesized conformance extension decls.

c163e0fe5e [Tests] Make OS features consistent 
lit.py currently allows any substring of `target_triple` to be used as a
feature in REQUIRES/UNSUPPORTED/XFAIL. This results in various forms of
the OS spread across the tests and is also somewhat confusing since they
aren't actually listed in the available features.

Modify all OS-related features to use the `OS=` version that Swift adds
instead. We can later remove `config.target_triple` so that these don't
the non-OS versions don't work in the first place.

7bfa01a817 swiftinterface: print _specialize functions with targetFunction parameter in .swiftinterface 
If we have an internal function with a `_specialize` attribute that has
a `targetFunction:` parameter we want the function to appear in the
.swiftinterface file such that the exported specialization can be picked up by
the compiler.

3aebf2850d [ModuleInterface] Ignore adjacent swiftmodules from the Frameworks folder

d3dbe75419 ModuleInterface: Introduce the %target-swift-emit-module-interface and %target-swift-typecheck-module-from-interface lit substitutions and adopt them in some tests that involve emitting a swiftinterface. The substitutions specify the additional flags -swift-version 5 -enable-library-evolution. There are a few motivations for adding these substitutions: 
- Tests that depend on emitted interfaces should generally use flags that are typical for modules that have textual interfaces (e.g. `-enable-library-evolution`).
- If a test is intended to produce a valid `swiftinterface` then it should verify that interface. This will help prevent interface printing regressions caused by compiler changes.
- Having commonly used substitutions for tests that emit interfaces makes it easy to experiment with compiler flags that might effect interface printing.

* absolute_import
* print_function
* unicode_literals
* division

f27005b8d0 ModuleInterface: When printing synthesized extensions, we need to be sure to guard them with required features if applicable. Not doing so can result in broken interfaces that do not typecheck because, for instance, a conformance can refer to a nominal type that is only declared when certain features are enabled. 
Also, fix a typo where `#elsif` was printed into interfaces instead of `#elseif`.
