[PATCH] D52659: [LLVM-C] Add an accessor for the "value type" of a global

[Robert Widmann via Phabricator via llvm-commits]

CodaFi created this revision.

Herald added a subscriber: llvm-commits.

Before this, there was no reasonable way to retrieve the type a global value (most notable, a function) was created with from the C API.
