    i386: define the AMD 'virt-ssbd' CPUID feature bit (CVE-2018-3639)
    
    AMD Zen expose the Intel equivalant to Speculative Store Bypass Disable
    via the 0x80000008_EBX[25] CPUID feature bit.
    
    This needs to be exposed to guest OS to allow them to protect
    against CVE-2018-3639.
