  -----------
  [X86] Fix TC_RETURN selection failure for Win+Thunk combination (#175977)

https://github.com/llvm/llvm-project/pull/158055 added a
IsNotWin64CCFunc predicate to these cases for reasons that are not super
clear to me, which causes selection failures as this combination is not
covered elsewhere.

Fixes https://github.com/llvm/llvm-project/issues/175965.
