llvm/test/Linker/constructor-comdat.ll
Rafael Espindola d7bb2de671 Fix logic for which symbols to keep with comdats.
If a comdat is dropped, all symbols in it are dropped.
If a comdat is kept, the symbols survive to pass regular symbol
resolution.
With this patch we do that for all global symbols.

The added test is a copy of test/tools/gold/X86/comdat.ll that we now
pass.
