        Description

        The current evbroadcasti32x4 method in assembler_x86.cpp has it requiring AVX512DQ and creating the opcode with an Op/En as T2. According to the Intel SDM, this form of the vbroadcasti32x4 only requires AVX512F (change to VM_Version::supports_evex()) and should use an Op / En value of T4.
