Introduce the "@llvm.dbg.value" debug intrinsic.
...
The semantics of llvm.dbg.value are that starting from where it is executed, an offset into the specified user source variable is specified to get a new value.
An example:
call void @llvm.dbg.value(metadata !{ i32 7 }, i64 0, metadata !2 )
Here the user source variable associated with metadata #2 gets the value "i32 7" at offset 0.
