Hi,
In this PR51928, it tries to look_for_tm_attr_overrides on a thunk but
there is no DECL_NAME for thunk. So it fails in
lookup_fnfields_idx_nolazy because name is NULL.

I hope the good way to solve this is to use the THUNK_TARGET instead of
the thunk itself. (or just ignore when it is a thunk?)
Tested on x86_64-unknown-linux-gnu.
Thanks.

I can commit for you, but the testcase is missing, though the changelog
entry for it is there.
