The SuppressWarnings flag, unfortunately, isn't very useful for custom tools that want to use the LLVM module linker. So I'm changing it to a parameter of the Linker, and the flag itself moves to the llvm-link tool. For the time being as SuppressWarnings is pretty much the only "option" it seems reasonable to propagate it to Linker objects. If we end up with more options in the future, some sort of "struct collecting options" may be a better idea. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@201819 91177308-0d34-0410-b5e6-96231b3b80d8
