PR gcov-profile/84107
* tree-profile.c (init_ic_make_global_vars):
Remove ic_void_ptr_var and ic_gcov_type_ptr_var.
Come up with new ic_tuple* variables. Emit
__gcov_indirect_call{,_topn} variables.
(gimple_gen_ic_profiler): Access the variable
and emit gimple.
(gimple_gen_ic_func_profiler): Access
__gcov_indirect_call.callee field.
(gimple_init_gcov_profiler): Use ptr_type_node.
* value-prof.c (gimple_ic): Use ptr_type_node.

PR gcov-profile/84107
* libgcov-profiler.c (__gcov_indirect_call):
Change type to indirect_call_tuple.
(struct indirect_call_tuple): New struct.
(__gcov_indirect_call_topn_profiler): Change type.
(__gcov_indirect_call_profiler_v2): Use the new
variables.
* libgcov.h (struct indirect_call_tuple): New struct
definition.
