Make function assembly more independent.
This is achieved by having clone_function_name assign unique clone
numbers for each function independently.
gcc:
* cgraphclones.c: Replaced clone_fn_id_num with clone_fn_ids;
hash map.
(clone_function_name_numbered): Use clone_fn_ids.
gcc/testsuite:
* gcc.dg/independent-cloneids-1.c: New test.
