      Backports

        Description

        These changes simplify frame management on 32-bit and 64-bit systems which support EVEX and extend more complete frame save and restore functionality as well as stack management for calls, traps and explicit exception paths. These changes also move CPUID queries into the assembler object state and add more state rules to a large class of instructions while simplifying their use. Many generated stubs and internal functions also now have predicated mask management for EVEX added.
