Thanks for taking a look. To clarify, this code was generated by our fuzzer,
but I believe the ICE is worth addressing.

The error here involves the combination of `__attribute__((target_clones))`
with `__attribute__((__weakref__))`, which triggered the internal error in
`ipa-visibility.cc`. It's part of a legitimate feature set that could appear in
real-world code.
