The idea is to provide an information in this fields on where the variable is
declared, like we we have in a DWARF output.
The data comes from
[Declaration](https://github.com/llvm/llvm-project/blob/main/lldb/include/lldb/Core/Declaration.h#L124)
object which returns line number as uint.
We only have (and probably only need for the purpose of variable annotation)
information on file name, line number and column number from Declaration
object. While LineEntry suppose to contain more information in it.
I think it’s better to keep this as a uint. What do you think?
