This reverts commit eb9f7c28e5fe6d75fed3587023e17f2997c8024b.
Previously this was incorrectly handling linking of the contained
type, so this merges the fixes from D88973.
This reverts commit 55c4ff91bd820d72014f63dcf7f3d5a0d3397986.
Issues were introduced as discussed in https://reviews.llvm.org/D88241
where this change made previous bugs in the linker and BitCodeWriter
visible.
Make the corresponding change that was made for byval in
b7141207a483d39b99c2b4da4eb3bb591eca9e1a. Like byval, this requires a
bulk update of the test IR tests to include the type before this can
be mandatory.
