I recommend extending testing via additional `RUN` lines to all of the following tests:
- `clang/test/CodeGen/attr-cpuspecific.c`
- `clang/test/CodeGen/attr-target-clones.c`
- `clang/test/CodeGen/attr-target-mv-func-ptrs.c`
- `clang/test/CodeGen/attr-target-mv-va-args.c` (already done)
- `clang/test/CodeGen/attr-target-mv.c`
- `clang/test/CodeGenCXX/attr-cpuspecific.cpp`
- `clang/test/CodeGenCXX/attr-target-mv-diff-ns.cpp`
- `clang/test/CodeGenCXX/attr-target-mv-inalloca.cpp`
- `clang/test/CodeGenCXX/attr-target-mv-member-funcs.cpp`
- `clang/test/CodeGenCXX/attr-target-mv-modules.cpp`
- `clang/test/CodeGenCXX/attr-target-mv-out-of-line-defs.cpp`
- `clang/test/CodeGenCXX/attr-target-mv-overloads.cpp`
- `clang/test/CodeGenCXX/attr-target-clones.cpp`

Note that, for many of the above tests, changes planned in #71706 will impact the expected behavior.
