Hao Sun has updated the pull request with a new target base due to a merge or a rebase. The pull request now contains two commits:

 - Merge branch 'fibers' into optimized-build
 - 8282792: Loom: Fix optimized build after commit 4d2710
   
   In commit 4d2710[1], one invocation of function print_frames() is moved
   from condition `!PRODUCT` to condition `ASSERT`. As a result, all the
   usages are now under condition `ASSERT`, leading to the compilation
   warning "unused-function" in optimized VM build.
   
   Hence, in this patch, we move the defintion of function print_frames()
   to condition `ASSERT`.
