[PATCH] D43380: [X86] Disable CLWB in Cannon Lake

[Gabor Buella via Phabricator via llvm-commits]

GBuella created this revision.
GBuella added reviewers: craig.topper, zvi, echristo.
Herald added a subscriber: llvm-commits.

Cannon Lake does not support CLWB, therefore it
does not include all features listed under SKX anymore.

Instead, enumerate all SKX features with the exception of CLWB.
