this_target_ira_int->free_ira_costs () is called by ira_init_costs,
but this isn't called after the compile, causing noise when running
under valgrind.
This patch adds a ira_costs_c_finalize function to clean this up,
and calls it from toplev::finalize (and hence this isn't called by
cc1/cc1plus/etc, just by libgccjit.so).
Doing so eliminates about 27KB of "leak" from the valgrind report.
gcc/ChangeLog:
PR jit/63854
* ira-costs.c (ira_costs_c_finalize): New function.
* ira.h (ira_costs_c_finalize): New prototype.
* toplev.c (toplev::finalize): Call ira_costs_c_finalize.
