Use function_arg_info for TARGET_FUNCTION_ARG_ADVANCE

Browse source 
There seems to be a bit of confusion around this one.  Almost all
callers pass the same arguments as TARGET_FUNCTION_ARG, meaning
that the mode is the promoted mode rather than the type mode.
But the calls.c handling for normal typed arguments instead passes
the unpromoted TYPE_MODE (despite passing the promoted mode to
TARGET_FUNCTION_ARG).  I've kept this behaviour with a ??? comment.

(The calls.c handling of libgcc functions does pass the promoted
mode though, as does the function.c handling of incoming arguments.)

Also, a couple of the arm callers don't seem to be using the hook
correctly.  Again I kept the current choices and added a ??? comment.
