Description
This is a followed-up task for the Vector API masking support after https://bugs.openjdk.java.net/browse/JDK-8264563. JDK-8264563 added the masked vector intrinsics for binary/store masked operations. Based on that, the c2 compiler implementation should be added for the masked operations. This only contains the C2 mid-end changes without any backend supports.
