Use function_arg_info for TARGET_ARG_PARTIAL_BYTES
This patch adds the function_arg_info class and uses it for
TARGET_ARG_PARTIAL_BYTES.
The hook is passed the promoted mode instead of the original type mode.
The arguments aren't mentioned in the documentation, which is why the
target.def change is so small.
The patch changes "true" to "arg.named" in:
gcc_assert (!epiphany_pass_by_reference (cum, mode, type, /* named */ true));
but epiphany_pass_by_reference doesn't care about the named flag.
