Range metadata applies to loads, call, and invokes. We were validating that metadata applied to loads was correct according to the LangRef, but we were not validating metadata applied to calls or invokes. This change extracts the checking functionality to a common location, reuses it for all valid locations, and adds a simple test to ensure a misused range on a call gets reported. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@220246 91177308-0d34-0410-b5e6-96231b3b80d8
