[PATCH] D62635: Add enums as global variables in the IR metadata.

[Reid Kleckner via Phabricator via llvm-commits]

rnk added a comment.

We did things this way to track which **enumerators** were used, not which enums were used. Size data showed it was worth doing (6%). The existing format doesn't support tracking usage of individual enumerators, so we pretended they were const integers to avoid changing the schema.
