Following the improvements in JDK-8255984, I think we can dispense with old-style allocation spike and GC penalties handling. JDK-8255984 is supposed to accommodate both cases now. This issue is to have a base for performance evaluation.

Additional testing:
 - [x] Linux x86_64 `hotspot_gc_shenandoah`
