[PATCH 0/3] MR198: ntdll: Fix unwinding on ARM in PE mode

[Martin Storsjö (@mstorsjo)]

Clang can generate SEH unwind info in PE mode on ARM now (since the very latest git versions of Clang 15). Add SEH assembly directives to let the unwinder step past handwritten assembly functions/trampolines.

Also fix a minor bug exposed by a testcase that I had missed to run before, and apply the same fix consistently to arm64 (where the same issue hadn't been exposed before).
