well as 2 files that use "Registrator"s. These are to be used by the MSVC builds, as the Win32 linker does not include libs that are otherwise unreferenced, even if global constructors in the lib have side-effects. Patch by Scott Graham! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@59378 91177308-0d34-0410-b5e6-96231b3b80d8
