Calling middle-end aggregate_value_p on a dependent type certainly is not the
right thing to do. It can't possibly do the right thing for various C++
specific type tree codes anyway.
I wonder if the easiest fix wouldn't be adding a bool argument to
allocate_struct_function, which would prohibit calling aggregate_value_p in
there and setting current_function_returns_{,pcc_}struct.
The C++ frontend would then pass dependent_type_p (restype) as this argument,
all other FEs and middle-end would pass false.
The C++ FE certainly doesn't need current_function_returns_pcc_struct value
in templates and current_function_returns_struct, while used once in the FE,
can't make much sense for dependent types.
