GDB doesn't have limitations, just bugs.  Something, in conjunction with 
changes to value_arg_coerce, should be added to the architecture vector.

One idea would be to break off much of the big bad switch into an 
architecture method (leave the pointer munging behind):
	struct type *coerce_arg_type(arch, arg_type, param_type)
with a default (that switch) of:
	trad_coerce_arg_type()
and then use that to figure out the type conversion (your implementation 
could call trad_coerce_arg_type() for the non-char/short case).
