Reid Kleckner fd1a7dfe04 Add comdat key field to llvm.global_ctors and llvm.global_dtors 
This allows us to put dynamic initializers for weak data into the same
comdat group as the data being initialized.  This is necessary for MSVC
ABI compatibility.  Once we have comdats for guard variables, we can use
the combination to help GlobalOpt fire more often for weak data with
guarded initialization on other platforms.
