Inlinable code is permitted to rely on these associated types, so we
need to make sure their declarations are printed in the parseable
interface.

- __SwiftNativeNSArrayWithContiguousStorage.withUnsafeBufferOfObjects
- __ContiguousArrayStorageBase._getNonVerbatimBridgingBuffer()
- __ContiguousArrayStorageBase._getNonVerbatimBridgedCount()
- Most __SwiftDeferredNSArray members
- HeapBuffer was at the wrong abstraction level, for no good reason. We have ManagedBuffer for the general case; we don’t need a slightly less general variant of it.
- Current usages of HeapBuffer are hyper specific: they all are flat buffers of AnyObjects, facilitating bridging. It makes sense to dedicate _HeapBuffer for this single usecase.
- Introduce a dedicate ManagedBuffer subclass for bridging buffers. This will make it slightly easier to recognize these in heap dumps.
- Inlinability audit.
The functions in LibcShims are used externally, some directly and some through @inlineable functions. These are changed to SWIFT_RUNTIME_STDLIB_SPI to better match their actual usage. Their names are also changed to add "_swift" to the front to match our naming conventions.
Three functions from SwiftObject.mm are changed to SPI and get a _swift prefix.
A few other support functions are also changed to SPI. They already had a prefix and look like they were meant to be SPI anyway. It was just hard to notice any mixup when they were #defined to the same thing.

A recent change made accessibility checking stricter. This had some
fallout on the half-baked @_versioned attribute, where we could no
longer define @_versioned members on a non-@_versioned type.
This was wrong anyway (and will be diagnosed when we add proper
diagnostics for @_versioned), because type metadata for the
internal type did not get the right linkage, but it used to work
as long as you didn't try to get the type metadata at runtime.
This patch adds @_versioned attributes to the right types now that
this broken behavior is gone.
As a result, _Variant{Set,Dictionary}Storage became resilient
(non-@_versioned internal types are not resilient), which broke
too many tests that assumed you can exhaustively switch over all
the cases. Since eager-bridging is going to eliminate this enum
anyway (or so I've heard), make it @_fixed_layout for now.
From the Swift documentation:
"If you define an optional variable without providing a default value,
the variable is automatically set to nil for you."
This reduces the amount of SIL generated for array operations significantly.
The generated code should be mostly the same (modulo different inlining decisions).
