Go back to intercepting kernel32!RaiseException, and only go for
ntdll!RtlRaiseException if that fails. Fixes throw_and_catch.cc test.
Work around an issue in LLVM's win64 epilogues. We end up with an
epilogue that looks like this, and it drives the Win64 unwinder crazy
until stack overflow:
call ill_cc!__asan_handle_no_return
xor eax,eax
add rsp,40h // epilogue starts
pop rbp // CSR
ud2 // Trap here
ret // Ret?
nop word ptr [rax+rax]
sub rsp,28h // Next function
Will file a PR soon.
