[PATCH] D34997: Keep metadata when changing Invoke instructions to Call ones

[Yevgeny Rouban via Phabricator via llvm-commits]

yrouban created this revision.

Metadata of invoke instructions get lost after SimplifyCFGPass.
Turning invokes that call 'nounwind' functions into ordinary calls the method changeToCall()
does not move or copy metadata from the source invoke instruction to the new call instruction.
This patch copies the metadata in changeToCall().
