X86 backend implementation does not enable maskAll instruction patterns for 32 bit JVM, due to which operations fall backs over replicateB operation which broadcasts the mask value in a vector and after unboxing-boxing optimization this vector eventually reaches to XorVMask which cribs since one operand is held in opmask register and other in vector.
