Hi all,

  can I get reviews for this change that factors out a few methods from `do_collection_pause_at_safepoint_helper` and reshuffles code from `gc_prologue`/`gc_epilogue` to be able to put those into parallel phase(s) later.

Testing: tier1-5



Commit messages:
 - Initial implementation of method reshuffling
