Detailed Description

Base class for non-instruction debug metadata records that have positions within IR.

Features various methods copied across from the Instruction class to aid ease-of-use. DbgRecords should always be linked into a DbgMarker's StoredDbgRecords list. The marker connects a DbgRecord back to its position in the BasicBlock.

We need a discriminator for dyn/isa casts. In order to avoid paying for a vtable for "virtual" functions too, subclasses must add a new discriminator value (RecordKind) and cases to a few functions in the base class: deleteRecord clone isIdenticalToWhenDefined both print methods createDebugIntrinsic
