Clang recently started using `FramePointerKind::Reserved` for Arm64 Windows: #146582
Flang translates this to `-mframe-pointer=reserved`:
https://github.com/llvm/llvm-project/blob/925588cd001a91d592b99e6e7c6bee9514f5a26e/clang/lib/Driver/ToolChains/Flang.cpp#L944-L946
However, Flang's command line parser doesn't handle `-mframe-pointer=reserved` (from <https://lab.llvm.org/buildbot/#/builders/207/builds/3284>):
```
