Reid Kleckner 8577eaf8e6 GlobalOpt: Preserve comdats of unoptimized initializers 
Rather than slurping in and splatting out the whole ctor list, preserve
the existing array entries without trying to understand them.  Only
remove the entries that we know we can optimize away.  This way we don't
need to wire through priority and comdats or anything else we might add.

Fixes a linker issue where the .init_array or .ctors entry would point
to discarded initialization code if the comdat group from the TU with
the faulty global_ctors entry was dropped.
