Use a combination of !associated, comdat, @llvm.compiler.used and custom sections to allow dead stripping of globals and their asan metadata. Sometimes. Currently this works on LLD, which supports SHF_LINK_ORDER with sh_link pointing to the associated section. This also works on BFD, which seems to treat comdats as all-or-nothing with respect to linker GC. There is a weird quirk where the "first" global in each link is never GC-ed because of the section symbols. At this moment it does not work on Gold (as in the globals are never stripped).
