[PATCH] D50166: [ARM64] [Windows] MCLayer support for exception handling

ssijaric added a comment.

I also moved the AArch64 specific changes to the Windows exception handling tables to this patch, as they are needed to get the test case to pass (they are required in order to populate .xdata correctly).  The test case also has a dependence on https://reviews.llvm.org/D51201, which adds HasWinCFI to the MIRParser.

There's also a dependence on making MachineFunction::HasWinCFI just a plain bool defaulting to false, instead of Optional<bool>.  Otherwise, some existing Windows test cases will fail due to not having HasWinCFI set which is checked during .xdata generation.  Reid, can you please submit this change as you mentioned it in https://reviews.llvm.org/D50288?  Alternatively, I can go through the failing test cases (about 10 in total) and mark the functions with the "nounwind" attribute.
