Reinstate "Nuke the old JIT." Approved by Jim Grosbach, Lang Hames, Rafael Espindola. This reinstates commits r215111, 215115, 215116, 215117, 215136. llvm-svn: 216982

XFAIL several MCJIT EH tests under ASan and MSan bootstrap. llvm-svn: 225393

Add EH support to the MCJIT. 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. llvm-svn: 181167

Move the personality function from LandingPadInst to Function The personality routine currently lives in the LandingPadInst. This isn't desirable because: - All LandingPadInsts in the same function must have the same personality routine. This means that each LandingPadInst beyond the first has an operand which produces no additional information. - There is ongoing work to introduce EH IR constructs other than LandingPadInst. Moving the personality routine off of any one particular Instruction and onto the parent function seems a lot better than have N different places a personality function can sneak onto an exceptional function.
