Description
JDK-8061553 added support for faster "heavy weight" locking paths. These paths are not currently used by JVMCI (or C1) leading to slower performance on programs that have contention in some code that does not suffer contention at a later phase (e.g. synchronized field initialization paths). These paths should be unified across C2, JVMCI and C1.
