This is needed if we compile StdlibUnittest with -sil-serialize-all
So far I added the imports only in files which needed them. But this may change, depending on the optimizer (inlining).
Adding them in all files doesn't harm and avoids confusion if someone makes an unrelated change which would result in such a linker error.
Add tests that would access Objective-C class metadata by casting and
generic type parameters. Also run these tests with the optimizer turned on.

This fixes a test failure when appletvos is not enabled. Also, stop trying to
link against a swift source file. This was causing the linker to emit a scary
warning.

Change ProtocolConformanceRecord::getCanonicalTypeMetadata() to return null if
the class metadata in the protocol conformance record is null. This fixes a
runtime crash in swift_conformsToProtocol when there is a protocol extension of
a missing weakly-linked class.

The goal is to test that we can safely cast to an Objective-C protocol that is
defined in a missing weakly-linked framework, even when the protocol
declaration is missing an availability annotation (this is common in
Objective-C frameworks).

These tests emulate deploying back to an older OS where newer APIs are not
available by linking to an Objective-C framework where APIs have been
annotated to only be available in the far future and then moving the famework
aside so that it can't be found at run time.
These tests include some basics (global variables and classes), but the focus
is on Objective-C protocols to validate the change allowing types to
conform to protocols less available than the types themselves.
