int_string does not support IS_SIGNED (1) for RADIX 16 anyway.
So I would simplify it just by using:

+  xsnprintf (p, endbuf - p, ",%s", phex_nz (len, 8));

This seems to be an unrelated cleanup, just drop it.

It is sure just for debugging but this is an output change due to zeroes
padding.  What about putting there instead:

const char *arg_type_len_s = pulongest (TYPE_LENGTH (arg_type));

and got for example:

-                      int: (t)->length
+                      long int: (t)->length

It has 26000 lines this way, I will try to reduce the diff size somehow.
