Martin Storsjo 5f14b6357b ntdll: Properly restore x29/x30 for arm64 packed unwind data with local stack. 
For the CR == 3 case, x29/x30 should be restored from x29, not from
sp, which may have been decremented further for local stack storage.

This fixes uwinding the stack for C++ exceptions in code generated
by MSVC.

Martin Storsjo 93ecc54ae5 ntdll: Pass a nonnull handler_data when continuing after a collided unwind on arm64. 
This fixes crashes when handling GNU/mingw style SEH based C++
exceptions on arm64; in these cases unwind_full_data ended up
where it tries to write handler_rva + 1 to *handler_data.

Martin Storsjo 93082b3d52 ntdll: Fix arm64 unwind across ELF/PE boundaries. 
The previous implementation might have given the impression of
working, as long in some cases where the PE code actually used frame
pointers, but turned out to be subly wrong.

This essentially reverts the functional aspects of 1c9fdaab0f.

Use the new value of the Lr register, after fetching the registers
from unw_step, as the return value.

To make single-stepping unwinding work properly, treat the registers
consistently:

- Make RtlCaptureContext store the current values of x29/Fp and x30/Lr
from within the function, not the ones backed up from the stack.

- After unwinding one step, first fetch the new values of all registers,
including the new value of Lr - then use this value of Lr to set the
new value of Pc (the address to actually return to).

This makes the unwinding actually coherent in reading unwind opcodes and
return addresses from one single function; previously these were out of
sync where the return address ended up being read from the function
one step further up in the call stack.

This fixes unwinding for setjmp for binaries compiled with clang
(in mingw mode).

Martin Storsjo ea9f47a767 ntdll: Properly return errors when failing to unwind. 
If libunwind is unavailable, make libunwind_virtual_unwind return an
error. Likewise if there was no PE exception info and we didn't try
unwinding using libunwind, we need to return an error when realizing
we were unable to unwind, instead of just warning and returning
success.

This fixes hangs/infinite loops on crashes when unwinding fails.
