After discussions on IRC, we've decided to pursue a different set of fixes for this and related issues. Essentially forcing the second link to have the same resolution, by aggressively dropping any non-prevailing defs. This will require a few fixes, such as enabling dropping non-prevailing non-odr weak/linkonce, enabling dropping non-prevailing weak involved in an alias, and ensuring comdats with non-prevailing copies are removed. The first new patch relates to the last issue (https://reviews.llvm.org/D28737).
