I thought that on amd64, we weren't going to have prologue parsers
and rely on frame unwinding info instead? At AdaCore, we have the
same sort of things because of Windows where the system code (mostly
system DLLs) does not have the unwinding info in DWARF format. But
for code generated by us, we have all the debugging information needed
to unwind without parsing the prologue, even on Windows64.
