gcc8-pr84739.patch
Untested fix. With different gimple_call_fntype the ICE doesn't reproduce,
because if there is a mismatch between func's DECL_ARGUMENTS and the actual
arguments, the current code already rejects it as tail recursion. In the past,
there used to be if (func == current_function_decl) condition and so what we
picked DECL_ARGUMENTS from didn't really matter, but now with the
recursive_call_p check it does.
