Hi,

I've committed the attached patch which implements 
cgen_symbol_at_address and cgen_print_address (in cgen_bi_endian_cpu). 
The implementation uses the loader's function? pin and current-function 
attribute (added previously for dynamic configuration) to determine 
which symbol is associated with the given address.

Previously, cgen_symbol_at_address simply wrote a message to cerr.

The disassembly for ports which use these functions now looks more like 
the disassembly produced by objdump.
