[PATCH] D37938: [X86] Remove unnecessary extra encodings from the CPU name enum in clang

[Craig Topper via Phabricator via cfe-commits]

craig.topper created this revision.

For a lot of older CPUs we have a 1:1 mapping between CPU name and enum name. But many of them are effectively aliases of each other and as a result are always repeated together at every usage

This patch removes most of the duplication. It also uses StringSwitch::Cases to make the many to one mapping in the StringSwitch more obvious.
