rnk created this revision.
rnk added reviewers: aaron.ballman, rjmccall, jdoerfert.
Herald added a project: clang.

After this change, clang spends ~200ms parsing Attrs.inc instead of
~560ms. A large part of the cost was from the StringSwitch
instantiations, but this is a good way to avoid similar problems in the
future.
