initialization of all targets (InitializeAllTargets.h) or assembler printers (InitializeAllAsmPrinters.h). This is a step toward the elimination of relinked object files, so that we can build normal archives. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@73543 91177308-0d34-0410-b5e6-96231b3b80d8
