I can't really tell, I am a bit confused by gdbarch_return_in_first_hidden_param_p vs
using_struct_return, and the fact that the AArch64 code also checks
language_pass_by_reference on the function's return value type.  You are suggesting
replacing the call to language_pass_by_reference in aarch64_push_dummy_call by
the result of gdbarch_return_in_first_hidden_param_p coming from call_function_by_hand_dummy?
Is it really equivalent?
