cgraph.h (cgraph_node): Add profile_id.
* cgraph.h (cgraph_node): Add profile_id.
* value-prof.c (cgraph_node_map): Turn into pointer_map.
(init_node_map): Rewrite to handle hashes increas of incremental
IDs.
(del_node_map): Update.
(find_func_by_funcdef_no): Replace by ...
(find_func_by_profile_id): ... this one.
(gimple_ic_transform): Do not remove useful histograms when
speculation is not done; dump info when indirect call removal
can happen at LTO.
* value-prof.h (find_func_by_profile_id, gimple_ic): Declare.
* gcov-io.h (__gcov_indirect_call_profiler): Replace by ...
(__gcov_indirect_call_profiler_v2): .. this one.
* profile.h (init_node_map): Update.
* coverage.c (coverage_compute_profile_id): New function.
* coverage.h (coverage_compute_profile_id): Declare.
* tree-profile.c (init_ic_make_global_vars): Make
__gcov_indirect_call_callee and __gcov_indirect_call_counters global.
(gimple_init_edge_profiler): Update prototype of
__gcov_indirect_call_profiler.
(gimple_gen_ic_func_profiler): Simplify.
(tree_profiling): Use init_node_map
