[PATCH 1/2] ntdll: Handle version 2 unwind info on x86_64.

From: Zebediah Figura

It seems this is identical to version 1, but with an additional UWOP_EPILOG
opcode.

Encountered while debugging https://bugs.winehq.org/show_bug.cgi?id=40285;
this doesn't help the application at all, but at least lets us get to the
unhandled exception filter instead of livelocking.
