Use function_arg_info for TARGET_FUNCTION_(INCOMING_)ARG

This patch makes both TARGET_FUNCTION_ARG and
TARGET_FUNCTION_INCOMING_ARG take a function_arg_info.
They have to be done together since many targets use the
same function for both.

The hooks are passed the promoted mode instead of the original type mode.
