[PATCH] D36904: Add llvm.label.annotation to implement MSVC __annotation

[Reid Kleckner via Phabricator via llvm-commits]

This intrinsic represents a label with a list of associated metadata
strings. It is not zero-cost, since it is modelled as reading and
writing memory.

MSVC does not clone annotations when inlining, so we follow suit.
