This gets exception handling working on ELF and Macho (x86-64 at least). Other than the EH frame registration, this patch also implements support for GOT relocations which are used to locate the personality function on MachO. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181167 91177308-0d34-0410-b5e6-96231b3b80d8
