Ideally from what point of view? Certainly not that of one where there is
proper separation between front ends and the middle end. There are no language
specific post optimization passes. From the point of view of the LTO front end,
whatever the ObjC-family front ends have handed over is language independent.

But those two L_OBJC_ImageInfo variables have a number appended. Is that
supposed to be so? Or is this LTO declaration merging at work and maybe you
want to avoid that?
(Maybe I'm talking completely non-sense, but something like that came up for
PR47259 also...)
