Emit personality function and Dwarf EH data for Win64 SEH.
Obviously the personality function should be emitted as language handler instead of the hard coded _GCC_specific_handler. The language specific data must be placed after the unwind information therefore it must not be emitted into a separate section. Reviewed by Charles Davis and Nico Rieck. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@185761 91177308-0d34-0410-b5e6-96231b3b80d8
