The old, incorrect one seems to have been added in d41ac895bb810d0b15844773cbecbf394d914010, with a similarly placed entry added in EnumTables.cpp in eb4d6142dcd53d79d8f8a86908a035582965fc52. This matches the value documented at https://docs.microsoft.com/en-us/visualstudio/debugger/debug-interface-access/cv-cpu-type-e?view=vs-2019. This fixes running obj2yaml on an object file generated by MSVC. Differential Revision: https://reviews.llvm.org/D100306
