LGTM. Maybe update the description with more background.

The test case was indeed passed with D105263 <https://reviews.llvm.org/D105263> but then failed since D107082 <https://reviews.llvm.org/D107082> https://godbolt.org/z/x4nq5bcWo
D107082 <https://reviews.llvm.org/D107082> changed the stack size of FR16(X) from 16 to 32 to workaround spill/reload problems. But seems it affects the COPY verification here.
