[RFT PATCH, i386]: Optimize zero-extensions from mask registers

Hello! Attached patch was inspired by assembly from PR 72805 testcase. Currently, the compiler generates: test: vpternlogd $0xFF, %zmm0, %zmm0, %zmm0 vpxord %zmm1, %zmm1, %zmm1 vpcmpd $1, %zmm1, %zmm0, %k1 kmovw %k1, %eax movzwl %ax, %eax
