The `log_on_large_pages_failure` function logs failures of large pages allocations. It reports to `log_debug(gc, heap, coops) `:

    // Compressed oops logging.
    log_debug(gc, heap, coops)("Reserve regular memory without large pages");

Memory allocated for CodeCache is not regular because it is executable. Failures of allocating it should be reported to `log_debug(codecache)` instead of `log_debug(gc, heap, coops)`.

`CodeHeap::reserve` has a regular memory reservation for _segmap which if it fails, it is reported to `log_debug(gc, heap, coops)`. Maybe it should be reported to `log_debug(codecache)` as well.
