6121477e - add support for storing just the inferred inlining_cost in CodeInstance (#58662)

add support for storing just the inferred inlining_cost in CodeInstance (#58662) In preparation for giving us the option of not storing code that does not seem useful immediately, but which we previously kept around just in case inference or codegen (always_inline) ever needed to decide if it was worthwhile to inline later. And also for investigating issues like the recently closed #58449 to examine whether the code was removed for either heuristic or correctness reasons.
