Implement the CPU vulnerabilty show functions for meltdown, spectre_v1 and spectre_v2 on Alpha. Tests on XP1000 (EV67/667MHz) and ES45 (EV68CB/1.25GHz) show them to be vulnerable to Meltdown and Spectre V1. In the case of Meltdown I saw a 1 to 2% success rate in reading bytes on the XP1000 and 50 to 60% success rate on the ES45. (This compares to 99.97% success reported for Intel CPUs.) Report EV6 and later CPUs as vulnerable. Tests on PWS600au (EV56/600MHz) for Spectre V1 attack were unsuccessful (though I did not try particularly hard) so mark EV4 through to EV56 as not vulnerable.
