Develop new data structure and code logic for holding profiling related information stored in the extent that may be needed after the extent is released, which in particular is the case for the reallocation code path (e.g. in `rallocx()` and `xallocx()`). The data structure is a generalization of `prof_tctx_t`: we previously only copy out the `prof_tctx` before the extent is released, but we may be in need of additional fields. Currently the only additional field is the allocation time field, but there may be more fields in the future. The restructuring also resolved a bug: `prof_realloc()` mistakenly passed the new `ptr` to `prof_free_sampled_object()`, but passing in the `old_ptr` would crash because it's already been released. Now the essential profiling information is collectively copied out early and safely passed to `prof_free_sampled_object()` after the extent is released. |
