This reverts commit 8247525471. While
correct, it has uncovered several issues in existing code bases that
need to be sorted out before we can land it again.
Fixes rdar://problem/57846390.
Today in far more cases we are using mangled strings to look up metadata at
runtime. If we do this for an objc class but for whatever reason we do not have
any other references to the class, the static linker will fail to link in the
relevant framework. The reason why this happens is that autolinking is treated
by the static linker as a hint that a framework may be needed rather than as a
"one must link against the framework". If there aren't any undefined symbols
needed by the app from that framework, the linker just will ignore the hint. Of
course this then causes the class lookup to fail at runtime when we use our
mangled name to try to lookup the class.
I included an Interpreter test as well as IRGen tests to make sure that we do
not regress here in the future.
NOTE: The test modifications here are due to my moving the ObjCClasses framework
out of ./test/Interpreters/Inputs => test/Inputs since I am using it in the
IRGen test along side the interpreter test.

* Migrate from `UnsafePointer<Void>` to `UnsafeRawPointer`.
As proposed in SE-0107: UnsafeRawPointer.
`void*` imports as `UnsafeMutableRawPointer`.
`const void*` imports as `UnsafeRawPointer`.
Occurrences of `UnsafePointer<Void>` are replaced with UnsafeRawPointer.
* Migrate overlays from UnsafePointer<Void> to UnsafeRawPointer.
This requires explicit memory binding in several places,
particularly in NSData and CoreAudio.
* Fix a bunch of test cases for Void->Raw migration.
* qsort takes IUO values
* Bridge `Unsafe[Mutable]RawPointer as `void [const] *`.
* Parse #dsohandle as UnsafeMutableRawPointer
* Update a bunch of test cases for Void->Raw migration.
* Trivial fix for the SceneKit test case.
* Add an UnsafeRawPointer self initializer.
This is unfortunately necessary for assignment between types imported from C.
* Tiny simplification of the initializer.
* Migrate from `UnsafePointer<Void>` to `UnsafeRawPointer`.

Leftover bits of SE-0055. Now that pointer nullability is reflected
in the type system, we can properly import throwing methods with
non-object pointer return types.
Note that Swift still won't let you declare them. That's coming next.
