Minimize clone counter memory usage in create_virtual_clone.
Based on Martin Jambour's suggestion:
https://gcc.gnu.org/ml/gcc-patches/2018-09/msg00111.html
gcc:
* cgraph.h (clone_function_name): Add a variant that takes a
tree decl.
* cgraph.h (cgraph_node::create_virtual_clone): Add a new
argument: num_suffix.
* cgraphclones.c (cgraph_node::create_virtual_clone): Pass
num_suffix to clone_function_name.
(clone_function_name): Add a variant that takes a tree decl.
* ipa-cp.c (create_specialized_node): Keep track of clone
counters in clone_num_suffixes hash map.
(ipcp_driver): Free the counter hash map.
* ipa-hsa.c (process_hsa_functions): Creates at most one hsa
clone per function.
