Remove SWIFT_RETURNS_INDEPENDENT_VALUE
https://bugs.webkit.org/show_bug.cgi?id=307531
rdar://170127262
Reviewed by Richard Robinson.
Wherever possible we want to avoid using the SWIFT_RETURNS_INDEPENDENT_VALUE
annotation, because experience has shown it can be error-prone.
In this commit we remove its use from core WebKit.
Three techniques have allowed its removal in this PR:
* For functions which return pointers: if Swift is aware that a type is a
SWIFT_SHARED_REFERENCE, then no SWIFT_RETURNS_INDEPENDENT_VALUE is
needed. In some cases, Swift was already aware, so we could just remove
the annotation.
* In one other case, Swift becomes aware of that fact so long as it can
see an extra file in the WebKit_Internal modulemap.
* For functions that return references, unfortunately that doesn't work
due to a bug rdar://168057355. In these cases, we temporarily have
to add extra functions that return pointers instead.
