This introduces a target specific streamer, X86WinCOFFStreamer, which handles the target specific behaviour (e.g. WinEH). This is mostly to ensure that differences between ARM and X86 remain disjoint and do not accidentally cross boundaries. This is the final staging change for enabling object emission for Windows on ARM. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@207344 91177308-0d34-0410-b5e6-96231b3b80d8
