Nullable return Spans did not include __swiftifyOverrideLifetime,
resulting in a lifetime error when returning the Span. Meanwhile return
values for __sized_by did not use the correct label for the call to the
RawSpan initializer, using `count` instead of `byteCount`.

Swift nodes imported from clang don't have doc comments carried over,
but IDEs are clever enough to fetch the comments from the associated
clang node. The swift node in the macro expansion from _SwiftifyImport
doesn't have a clang node directly associated with it however.
This patch adds the same comment from the clang node to the
_SwiftifyImport macro invocation node. Since the macro has access to
this node, it can easily copy over its leading trivia.
For now the comment is not altered at all, meaning @param still remains
even if the parmeter is removed.

_SwiftifyImport doesn't know how to handle
AutoreleasingUnsafeMutablePointer, so we should not attach any
.countedBy information for pointers that are imported as this type.
This also adds defensive checks against adding .countedBy to any pointer
type that _SwiftifyImport doesn't know how to transform.

This passes along the noescape attribute to @_SwiftifyImport as
.noescape(pointer: .param(X)). This allows importing parameters as Span,
MutableSpan and RawSpan.
This makes it possible to mark a pointer with __sized_by when the
pointee type definition is not included. The wrapper function has the
same interface as if the parameter were a void pointer, since the stdlib
has no `OpaqueBufferPointer` type.
* use swift-ide-test for checking interop signatures
* add xfail test for Span + Optional combo (Optional requires Escapable)
* Make pointer bounds non-experimental
* Rename @PointerBounds to @_SwiftifyImport
* Rename filenames containing PointerBounds
* Add _PointerParam exception to stdlib ABI test
* Add _PointerParam to stdlib API changes
* Rename _PointerParam to _SwiftifyInfo
