[PATCH]: Use 16-bit int for hc11/hc12

Hi!
For HC11/HC12, the `int' can be 16 or 32 depending on gcc -mshort option.
Since the current dwarf2 reader does not take into account the size
of basic types, the definition of `int' is often wrong for hc11/hc12.
The default in gdb is 32 but most people are using short ints (16).
The patch uses that to be correct in most common cases (while waiting
for new dwarf2 reader).
I've committed this patch.
